*shrug* Can't say I've ever seen evidence for or against this, other than Visc being banned a few times. However, I know for a fact they can ban CD-keys from logging into their master server (as the master server for the website is the same one used for logging into NWN). Perhaps they just usually don't?
But used the same CD-key, and trolled with it in the past? That stuff isn't hard to figure out, and frankly I much prefer the more moderated feel of the BioBoards to the "You can get away with anything" feel of Obsidian. That's the developer's choice though.
Never really had a problem with it, personally. I just post links to images when I need 'em.
I agree, this sucks.
Anyway, enough hijacking.
