Admins should start locking threads which don't serve any purpose. They can start with the gambling section so the topic created with the title "What is your favorite gambling site" in 2013 can stop spammers from posting.
I think there is a new thread with the same question "What is your favorite gambling site?". In my opinion it is clearly their scheme to be able to increase their post count by creating a thread until the thread will have more pages used for every person who reply in the thread when answering. I don't disagree locking threads that it's not helpful anymore or doesn't have purpose anymore.
