If you want to stop the spam, just make it where a New Poster cannot start a thread until after they have made X amount of post, X amount of days or both
You could also prevent more than 1 new thread per 10 mins or even per hour. eitherway its why I cancelled my account a month or 2 ago, then resubscribed a couple days ago and not looking good at this point. Its sad a lot of the posters from this forum have some great insight.I think that after 20 consecutive threads promoting their ****, it's already pretty obvious. Might be too much work though. Traffic is the name of the game. Dang almighty it's gotten bad here recently.
