Hello! My name is Akihisa Ito, aka ap12, and I am the operator of the criminal organization "Black Cat Server@ap12!! The criminal organization "Black Cat Server" to which I belong contributes to society every day! We operate VOICEVOX text-to-speech bot and VOICEROID text-to-speech bot, collect messages collected via bots and personal information of members, and sell them to hackers!

I suppose they're trying to sow fear or something? Like "your data isnt safe" which is bs.

It's just bots or spammers generating accounts on various instances (<- edited for clarity and correction) then using them to spam popular communities. Happens pretty regularly, but unfortunately if the home instance doesn't ban the user then each instance has to remove the spam themselves.

Also, there's no way to report a user to their home instance so long as they don't post anything in a community on their home instance. So the only people who can ban them in a way that federates to other servers also doesn't know unless someone sends them a personal message. And they are using a bunch of different instances to make it hard to do that.
