Thanks Stuart from NichePay and the posters for this thread:

Most of these ideas are good ones, it's a problem that has to be fixed. We need to limit the number of posts one poster can make to these threads. I hate worthless posts. There needs to be a limit as to how many contests run concurrently, and the 'whoever has the mosts posts in this thread wins' has to go.
I agree that only top advertisers should able to run contests.
 
So, new rule #1: No 'whoever has the mosts posts in this thread wins' contests. 
Next rule: Limit on how many times and how frequently someone can post in a contest thread. What should that be? We don't need non-webmasters coming in here and taking over these contests.
Next rule: How many concurrent contests should be allowed? And how long can they last, maximum?
