I just took a look in there to see if there was a batch of them we missed, but from what I see in there, at least in terms of new created threads we've been pretty good about removing them. There is one thread in there, the "crowdsourcing" one, which is kind of questionable as it is a post by a 1 post person to promote their site, but on the other hand their site is game related, and they didn't spam it so I don't really have a problem with that one particularily.
If you see others I missed, please as Nizdaar advised, report them.
