I think you should not make an open statement of scam since your are still making an enquiry from the body of your post until someone who can give full details about the site does that.
If you are alleging scam already then you can put a post on that with prove in scam accusation board.
Alright both of you are simply spamming for signature campaign purposes. You haven't looked into the issue at all, and I'd know if knowledgeable people who know about the subject area could help here. Not people that are just going to post generic garbage with no real value.
