See the section called "Spam Cops". Once you've done some research and are sure something fishy is going on, make sure to call out these people in the comment section on their threads. You should be handsomely rewarded with Upvotes.
Anyway thanks for this post. You are doing the whole community a good service when you expose scams. We need this place to be kept legit.
