I just did a quick look over the forum, and after many skimmed threads I only found one mention of Linemarvel or his games. It was the expected thing, a few members pointed out LM's games and said they were decent, but were quick to state their loyalty to ToonPimp and praise his work as being in a league above DG. Let em think what they want, but I'm not sure which hate filled threads your talking about.
I can't say I much liked the look of the site or it's evidently younger members, but I don't feel trolling them is going to do any good. In the end they are an unlikely community like ours. Rivals in a weird sense I suppose, but at risk of sounding like a fun killing hippy, no sense in making needless enemies.
