I'm actually very happy about the fact that I *don't* see those threads - if I want that, I use the search tools or go to the respective section of the forum, that's easy and straightforward. This forum is about photography, it's not a marketplace in the first place, is is? Besides, there are enough GAS incubators around here anyway, no need to further fuel the fire ...
I more or less gave up on other boards that featured Buy & Sell threads prominently, drowning out the interesting stuff.
