You can make a post on Scam Accusations if you feel someone is scamming or wrongdoing in the forums.
This topic is about a request that the forum moderates scam, not a scam accusation, so it belongs here. The Diggit.io is just an example.
And scam accusations are opened only after the scam happened, so at best they are damage control. And it is far from being the most visited section in the forum.
