If the sort of crap that I've seen in GM lately is allowed there, then surely exho threads, which are actual matches,
I agree that there's currently too much crap in GM.
However, the exho threads are not actual
matches given the fact that which player is going to win which match is clearly settled in advance. They can still be fun to watch at times, so I think it's a good thing to keep those threads away from the very messy GM where currently, it seems that there's a competition going to see who is the best wind-up merchant. Most of that crap is somehow related to tennis.
