The MorphMarket Ratings system only allows reviews on inquiries through the site, by design, so the information there is more highly scrutinized than a forum (just as @blacksideballpythons said). It does allow feedback on sellers and buyers, although we do not currently display all that information about the buyer so that side is more limited. For in depth discussion it allows linking to the FBI or BOI forum.
I am considering adding a Customer Review/Alert section for MM members only, primarily for broadcasting alerts about scammers. However, I’ve decided to hold off on this at the moment because these types of forums are the most volatile and we have enough going on getting this community up and running that I don’t want the added difficulty at this time.
