During DH, strenx was playing someone (I think av3k, maybe cypher) and he TF'd him, which led him to apologize many times to [his opponent] after the match. I'd never seen someone apologize for a TF. I've never been apologized to over a TF so it just made me wonder if there's a "rule" among players about it- trying to avoid it, etc. I'm guessing its taken as a sign of disrespect, if done on purpose during a tourney/cup/etc?
