About us

Sakurajima Social (桜島SNS, さくらじまSNS, Cherry Blossom Island Social Networking Site) is a Sharkey/Misskey server for the English Japanese-media and Anime/Manga/Japanese Media blogging/video creator/podcaster community. Sakurajima Social is a spinoff of Sakurajima (sakurajima.moe), the Mastodon server. This is the place to talk about anime, manga, light novels, video games, and other Japanese media in a comfy and inclusive place. Of course, you can talk about anything as long it doesn’t break the rules. This place also gives content creators (bloggers, podcasters, and video creators) a place to share their content. All are in a safe place, free from hate, trolls, harassment, extremist ideologues, and illegal content.

This is a highly moderated server and operated by an Asian-American who is on the Progressive Left. We only defederate servers if they are deemed a high risk (hate speech/spam/trolling risk/harassment/illegal content) or certainly break our rules. Otherwise, we moderate rule breaking posts if reported by users or discovered by moderation staff. See the moderation section for details. Note that we only block servers if it breaks our TOS, not for any other reason.

Note Federating with Sakurajima.social is not guaranteed for servers that are not following the Mastodon Covenant. Links between federated servers are temporary and may change or disappear at any time. We will block, suspend, or silence any server which permits any of the content or behavior prohibited by this server.

Relay Information

Sakurajima has a private relay containing only servers the owner has trust with and the server owners agreeing to join. Here is a list of servers that are in our private relay.

sakurajima.moe (main Mastodon server)
sakurajima.social (our Misskey/Sharkey server)
urusai.social (our friends, Anime-themed Mastodon server)

Don’t ask to join, the owner will only ask if you want to join, and the server must already be following the Mastodon Covenant and must be Japan or Japanese Culture related.

Mastodon Clients

Suppose you find the default web interface difficult. Once you register an account, you can use a third-party client instead of the Mastodon web interface. To log in to your account in these apps, specify “https://sakurajima.social” as the server server to log in. While Sharkey as Mastodon API compatibility, not all functionality may work.

Any Misskey client will work with Sharkey in addition.

Mastodon Covenant

This server complies with the covenant. The user data is backed up daily (excluding media, as that, is stored in Object Storage at Linode) via daily backups with Linode/Akamai Cloud. Current and last seven days of database backups are stored on another server. Any backups to the external server are also backed up at Backblaze.

We have a zero tolerance policy against hate speech and harassment. See the moderation section.

Moderation

See Server Rules page or rules section for the most up to date information on rules and enforcement.

Block list is only viewable at our main website and not search engine discoverable. The list is for informational purposes and not the most up to date as this is only updated once a month. The list is not viewable here due to a tool used to scrape the list used for nefarious purposes.

For servers that follow the Mastodon Covenant, we will moderate only by user basis as they are required to moderate against hate speech and harassment. These servers will always be on the allowlist (but can be limited/silenced due to spam-bot attacks).

Otherwise, we will silence (if the server’s administrator interacted with bad servers with rule breaking interactions, but don’t post rule breaking content) or if the contents will surely break the rules, defederate. To avoid getting silenced/defederated, block all Fedinuke servers, which are considered worst of the worst and ensure your server is moderated sufficiently.

Note that edgy behavior, or skirting the lines of being a troll will most likely violate our rules, especially in regards to hate speech, harassment, and abusive behavior. This behavior is highly discouraged. If you planning on enganging in this behavior, it’s recommended to find another server.

Note that we do not remove any blocks unless it’s by error (evidence is required to prove this), which is unlikely as we use trusted sources for block lists. server owners may appeal, but substantial evidence is required and we will audit your server. If we deem the block as legitimate, we will not answer your request.

Blocklist Explanation

Federates with the usual suspects/Alt-fedi – used when an instance federates with, associates with, and shares the culture of, instances that don’t moderate (and in many cases, actively support) things like harassment, bigotry, hate speech, trolling, far-right ideologies, and generally abusive behavior. Thus, behavior that will break the Mastodon Covenant regarding hate speech and harassment. Sites are considered alt-fedi when the admin made three TOS breaking interactions (e.g. boosting or replying to hate speech) with Fedinuke sites.

DNI – ‘Do Not Interact’; instance hosts illegal content such as CSAM, loli (on non-Japanese servers, for Japanese servers, this is handled by a per user basis and we use text/hash tags filters), pedophilia, etc. If you want to verify these blocks, proceed with caution; use a VPN or an anonymous browsing service like Tor, and purge your cache afterwards.

Fedinuked – Considered worst of the worst servers, which contains hate speech, extremist content, and harassment, which of course violates our TOS. Receipts are available here.

Sources we used in the consideration of adding servers to our block list: Fedinuke and new additions from pleroma.envs.net. No block lists are automatically imported, we manually inspect them before they get added to the list.

On the moderation list, there are two type of blocks, Limited/Silenced and Suspended.

Limited/Silenced – You can follow users from this server, but all messages from this server will not show up on the federated timeline, hashtag results, and search. You will not receive any notifications or direct messages from Limited/Silenced servers. You need to see the profile directly or follow a user from that server to appear on your Home timeline.

Suspended – No messages will be exchanged with this server. It’s not possible to follow users from suspended servers nor posts from this server will appear on this server.

Server Exceptions to Rule 4

On Sakurajima Social, we use the sensitive words feature in Sharkey/Misskey to remove loli and shouta content from the timeline and tag search. If posts contain the words related to loli and shouta will be set unlisted with any discovery features removed.

In regards to rule 4, accounts that are on servers specified on the list whose users post lolicon/shoutacon that posts loli/shouta and not removed from the public timeline from our filters will be limited (removed from the public timeline). Since this is a Japanese-media centric fandom server, we will only make an exception for the following servers (not an exhaustive list):

Misskey.io
Misskey.art
Misskey.design
mstdn.jp
fedibird.com
sushi.ski

Note: Pawoo is defederated due to rampant instances of CSAM.

Regardless, boosting of lolicon/shoutacon is prohibited, user may be warned and/or punished if they do so. Any servers outside of Japan that serve lolicon/shoutacon content will be suspended consistent to our policy.

Actual CSAM content (including AI generated) is still prohibited, regardless if users are on the servers mentioned on this list. Boosting/Favoriting/Reacting to lolicon/shouta content will result in a warning and/or ban.

Automated Posting

While bots are allowed, note that your bot can only make up to 4 public automated posts in an hour. No more than 16 unlisted posts in an hour.

If you flood the local timeline, we may limit/suspend your account temporarily and you may appeal once you resolve the outstanding issues.

Note: This rule does not apply to apps that auto-shares blog posts or RSS feeds. Non automated posts made does not count towards this limit either.

Content Warnings

Content warnings (CW) allows users to hide suggestive or potentially triggering content. This requires the user to hide the content by default. If thee user wants to view it, they can click the button to show it.

The following requires a CW and sensitive always:

Sexual themes (including nudity) or content
Violent themes or content, blood and gore
Content that contains self-harm

Suggested, but not required, or at least tagged (for purposes of filtering):

Political current events such as elections and government actions (normally abbreviated to ‘pol’ along with the country/region, ie. ‘UKpol’, ‘DEpol’, etc.)
Potentially triggering Mental Health topics (normally abbreviated to ‘mh’). Many of our members come here to discuss their mental health journey, and we seek to be as welcoming and open as possible, but for the sake of other users: please CW references to self harm, suicide, helplessness and other moods and behaviours that may be contagious or trigger people in recovery
Alcohol (‘alc’) and drugs
Themes or content about abuse
Common phobias (Like certain animals such as snakes and insects.)
Spoilers (in regards to source material not covered in an anime or for an episode that just aired)
Long posts or posts with multiple parts (please also use the ‘unlisted’ privacy setting for posts after the first in a thread, so that the local timeline doesn’t get flooded)
Content made with generative tools like neural networks (“AI”) and dissociated press/ebooks bot-style Markov chains that are designed primarily to imitate art or communication made by people. These can cause an uncanny-valley effect and can be distressing or frustrating when presented without warning. Additionally, AI generated content (text and image) must be tagged, no exceptions.

Please do not demand people to CW content, especially if it’s not required by the rules, this is the moderators job. We will send a DM asking the content to be CW’d.

Creator and Business Accounts

All creator (consisting of more than one member) and business accounts must be Japanese Media/culture related. Any account that is created that falls outside will be suspended immediately and appeals will be rejected. No Exceptions. This rule does not apply to individual accounts, except if the user is creating an account for a business.

Business accounts can only be from a small business. If you are a creating an account for a medium/big business, please use a different instance as we do not have the capacity to host you.
