I ran a website like that, it was all scammers.  On both sides.  I left because I didn&#x27;t want my name attached, but it organically attracted both scummy type 1 users and scummy type 2 users, where both were necessary for interaction to take place.<p>EDIT: I should add that I wasn&#x27;t made fully aware of the depth of the scamminess of the whole thing until I accidentally tried cleaning up some &quot;offers&quot; and found it was all scummy offers to scummy counterparties.
