Honestly, it doesn't bother me. I prefer it being the Wild West. If some douche wants to sign up just to try an unload an "OMG R@RE! SE@LED KEITH COURAGE!" for $800, let 'em try. Instead of getting our undies all up in a bunch and acting like internet rage nerds, we can just point, laugh, and move along.
And at first I was was okay with making a 150 post minimum to use the Buy/Sell boards. But shit, if some guy actually comes here with something good to sell and is willing to do so for a fair price, why make him wait until he has 150 posts?
Sorry, but I say we just let the community filter out the bullshit in this case.
