There is another web developer forum that has been all but ruined by these kinds of posts, many on the topic of SEO ("What is the best SEO?.... and here's a link to my SEO company"). They seem completely obvious to me, but I am surprised when I see "regulars" answer them.
I sure hope the management of this forum manages to create a process to address it. So far, I have seen relatively little of the garbage on this forum, perhaps it's already been handled pretty well.
