There is a spate of #AccountTakeover underway.
Service providers may receive reports for accounts that have a display name beginning with "Hacked -" or linking to "t[.]me/HomeFucker5"
These accounts may be longstanding valid accounts that have been hijacked.
While investigating, consider
1. deleting any offensive posts,
2. freezing the account until the rightful owner can reclaim it,
3. use of two-factor authentication for accounts shown to be at risk
