Here follows the text of a PM from Tommy on the RevLeft boards (which apparently are good for something besides generating lame tendency wars and chit-chat). I had asked him:
"So apparently you're banned on the PI forums now? What provoked that?"
He responded:
"I'm not sure. I assume it is for mentioning Israel or the Gaza Strip on the OT topic on the Egyptian revolution. Or it might be for calling for Mubarak to be hung in the same topic.
I can't access my PMs so I can't know for sure.
The ban expires on the 2nd of February.
Could you pass this on to someone who can post in my AAR and put people's minds at rest?"
P.S. Your guess was the closest. You should get a cookie or something.
