Joey seems like more of an instigator, but revenge team wounding is just as much against the rules, and it makes decisions more difficult when you yourself have been recording breaking the same rules you are asking others to enforce. I think it takes the wind out of this thread's sails, and would have to leave it at a warning for both of you. Or a banning. Up to you.
I'll have someone check the logs to clarify the scope of Joey's griefing
