Surely I can't be the only one that finds that possibility a little worrying?
TBH, at one point it did look like Scott had registered under multiple IDs. I don't think it was a group ban in the sense you're taking it -- the mods are very diligent before re-banning Scott, but if you've got a whole bunch of people whose posting style looks like him, you haven't really got much choice but to suspend 'em all and then un-ban 'em as you can establish their bonafides.
I thought that was called free speech?
You absolutely have free speech. If you want to start your own discussion forum, or post to your own blog.
Here, you, I, the Professor, and everyone else, operates at the sufferance of Rebellion who are entitled to make any judgement they choose about the best way to represent and protect their properties.
Note that I have disagreed with them vehemently on this very point in the past and am still here, so, generally speaking, they're pretty laid back.
Cheers
