You can read this thread if your account got hacked :
Recovering hacked/lost accounts. And during the recovery process, you can give red trust or create a flag on your hacked account, so that people who want to transact with that account will be more careful. Let say, the red trust and flag as an alert.
Yeah sure, thank you for this, I'll do it. Can the red trust be removed later? I mean after I recover the account.
You should warn fast when your account was hacked, then some DT would give some warning by temporary tagging the account. So that nobody can try to deal with the account. But You can not do it. Even you can not create any post in Meta(I am not seeing any post made in META by this account).
BTW it is not sure that the red tag will be removed or not. It depends on the user who tagged the account. But if you can prove that your account was really hacked and the hacker scammed people then there have more chances to revise the tag.
