Ehh....I think I know who you're talking about, but if it's who I think it is, he hasn't been as active as he was for most of the year, so that's an improvement. Plus all the raging trolls are on my ignore list anyway, so I don't tend to read their threads or comments. I've suggested people put these assholes on ignore and not to even peek at their posts, but that didn't seem to catch on and I've even broken my own rule occasionally (though not lately).
There is a rule against trolling, but apparently you-know-who's posts don't rise to that level in the moderators' eyes. And I'm all for freedom of speech on the forum--it's one of the things that attracted me to it in the first place. So I really don't have a problem with whoever you're talking about doing his little rants and whatnot. I don't have to look at them if I don't want to, nor does anyone else. That's what the ignore button is for, no?
