i had my first downmod in ages, and it dropped my karma below 50. apparently somebody thought i was trolling. i had finally had enough of the complaints of "it's not news for nerds/it doesn't matter" when an obituary gets posted, so i went off on a rant on somebody.
my guess is that the parent was modded down (and it was), and somebody saw my post out of context, and moderated it stupidly. either that or somebody thinks that using the word jackass in bold type makes you a troll. hopefully they'll get theirs in M2, though.
