It is one of the problems with social media, one can react in an instant when they are emotional about something...good or bad. The other is that even if the moderator removes the posts, they are still accessible for eternity. Once anything is indexed there is a record of it for ever. Not many people are aware of that. Old obsolete and "deleted" post resurface from time to time. The more places it is posted the more widespread its effect.
So the damage though not intentional is longer lasting than the short period of time it appears on the various forums. How else do you think the authorities can track everything anyone has ever posted online? It stays forever!
Glad you got your situation squared away. Let's hope no unrepairable damage was done.
