greetings.

I discovered there're a mailcious user account registered on your server:

DarthPutinKGB

that user performs illegal adding itself to users following lists across the Fediverse (without user following request, this is some vulnerability in code, I guess). moreover, it tries to change user statuses and to send messages from other users names, which fail because of key signatures check. I checked logs on my server to get this all.

I had seen more complains on it from other users on other servers.

I strongly recommend to delete that account and possibly ban its IP, if it's known.
