The forum has the same internet problems that all do - insults, trolls, weird obsessives etc.
But the mods do a difficult job very well - if there was less moderation you'd have the bleacher report cesspool, if there was more you'd have the Orioles hangout wasteland.
Specifically related to Boxcar - he's the poster child for the internet personality of "if you have a different opinion to me, then you're a retard" but to be fair to him, he normally apologises if he goes too far, and he doesn't just shitpost.
