Please note: If you are posting on spam mega threads, I will possibly not count that post. There are some threads that generate a lot of repetitive garbage, I won't count such repetitive posts in a thread as eligible for pay. So, please make sure you are not going to miss the pay because I deny counting some of your posts.
My suggestion:
I think you need to be clear what the criteria you are consider spam mega threads because almost all the thread in gambling boards are more than 5+ pages, they can have an option to create a new thread about gambling. But mostly it's pointless thread and I'd say that's more spammy than replying 300+ pages of sports thread.
