To be specific, someone using the AngryModem id posted a link to tubgirl on MoFi.
I've said before that I personally don't have any problem with goatse and I think it's funny that other people do. But, hey, other people do. Other people are deeply offended by it. So, when the whole point is tricking people into seeing something that deeply offends them...that's being a jerk. It's not complicated. The mean-spiritidness of angry_modem doing that to MoFi is appalling, and it's not completely independent of MeFi because he's as much as said that he did it because he wanted to offend MoFi, which he doesn't think much of. MoFi has been much discussed in the past two days, angry_modem signed up at MoFi as angry_modem, at a site similar to MeFi, and posted something there that is explicitly ban-worthy here. Just to piss them off.
On the konolia matter, here we have angry_modem owning the wilwheaton.org domain, and konolia being a very unusual name (google it). And konolia's said she googles for konolia from time to time and likes wilwheaton...lo and behold, someone posts a fake link to goatse on wilwheaton.org. What are the odds?
The issue is being someone who likes to wind people up, has an affinity for scatological and trangressive humor, and is malicious. So he didn't do it here and it's not appropriate or sensible to sanction him here. Makes sense. That doesn't mean people don't have a right to be pissed off at him. He deserves it
