i see plenty of people from forums and while i may not agree with everything that is said here, i will team and play with anyone, until of course, they demonstrate its not going to be a pleasant experience to continue doing so, even then i can't imagine keeping up with any exclusion, just seems petty and unimportant when there's usually several more in the groups/leagues to engage with, thus avoiding the issue you probably have entirely,
but i certainly would never make that judgement from a forum post..
