Bilbert, I think you need some new glasses:
It's not clear exactly how many people have been affected, but it includes nearly 170 professional players in the TF2 UGC league.
It does not say prestigious anywhere! No need to be a dick to a league you might not appreciate or even play in :X
And barely anything in comp TF2 is professional as there are not many players with actual contracts and there definitely were some pro players in the mix that got banned.
