We have seen a recent wave of impersonation accounts which claim to be another fediverse user, often with a similar username and boosting some posts from the original account, before reaching out to followers over private mentions and claiming to have issues with their original account.

Please report them if you see them!

@staff I had an account through med-mastodon. The server looks like it is under maintenance since 12/28. I found out that it may be history, so I am using my other mastodon account with the same handle which I created when I first was trying out Mastodon. I kept my same handle/username. I am not boosting posts from old account or doing private mentions. Just saying that you may see new accounts now under the same username bc a server went down.
@huskify Users having accounts on multiple servers or moving servers is not unusual, though the behavior of these impersonation scams is. Your moderation team will be able to tell the difference! However, we want users to be extra vigilant they do not fall for a scam around someone claiming to have moved accounts.
