Yeah, we're aware. We spend an inordinate amount of our time fighting spam here. It's the unfortunate consequence of a) being a really large forum that gets a lot of traffic, so we make a nice target and b) using one of the most common forum platforms on the internet.
We've put in various roadblocks and other things to make it harder for spammers, but the unfortunate reality is that we're a big juicy target for their crap, so it's worth their time to find ways.
The best thing you guys can do, as always, is hit the old "report post" button and let us banninate them.
