I have a forum at Hardcore Hyzers.com I dont ban spam as long as its disc golf related and goes in the Buy and Sell section of the forum. Its a very small forum, but the only way to make it better is to have people leave their thoughts, comments and ideas.
Hopefully, any PHP based stuff gets updated on a regular basis to close up some of those holes. I got no complaints about the current implementation. Maybe some more options on ordering the list of forum posts is about it.
