Reason one: Trolls are everywhere, and even more so in clubs. People cry every day about getting their club ban-attacked, and there are plenty of individuals who fall under the "troll" category. Don't pretend that trolls are mostly on OTF.
Reason two: The forums easily have better thread quality. Even though yes, there is way too much spam and whatnot, there are great threads for everyone to participate in. OTF threads are very rarely copied, and you've used a poor example in my OTFDAN club, as only a few people have tried copying it. But who cares?
Reason three: The environment of OTF is easily much better also. There may be fights going on about people not wanting under 500 elo players to be on OTF and other posts like that, but it's a great community where everyone for the most part gets along and works things out. We comfort each other when people are having a hard time.
Now, why are you trying to start an argument anyway? You started out as a spammer here, but seem to have gotten popular with clubs and seem to feel better than all of us on the OTF side of things. Why does OTF seem to bother you so much that you have to hate on it every time you come online?
Oh I misread your tone entirely.
