Rather than carry out and open scams many scammers pretend to be a bonafide business but behind the scenes they are criminals waiting to sting their next customer playing the long game.
Thanks to this deed, they and The Rock Trading are completely burned on this forum.
One of the Administrators of the Forum (I think mediators can't do this) downgraded their only positive feedback from a single member (who, by coincidence, promotes The Rock Trading on his signature) to untrusted. This wasn't an innocent move and doesn't promises anything good for them.
It's no coincidence that he never posted again.
