Need advice: static imploding because of cheater.

I think you could have pulled him to the side and asked him cease and to delete that vod. A simple conversation can work miracles. Now other people will probably be wary to raid with you as you have now been labeled a snitch.

Or at the very least, label them problematic and incapable of solving issues without creating drama. Seriously, how awkward can you get? No one wants someone like that on their team, much less at the leader of their static.

The whole discussion around 3pp here is just a symptom of the greater issue: OP's inability to lead and solve issues as leader of a group without creating a mess.
