Hey, make sure you set your group admin permissions to "Subject to Vote" or "Are Not Allowed". There has been two notorious group hijackers for over a month now who apply as a co-founders, delete all the artwork in the gallery and favorites, and replace it with gore, scat and porn.
I am currently not accepting any cofounders or only allow people I am familiar with so I don’t believe that should be an issue. I delete/ban people who are trolling when I see it happen. You can message me if you have concerns
