People who are not SGAs cannot view the info for clean players.
I searched the name DaGraveFilla. It does come up with one clean GUID on that same, and there is one linked GUID that is banned on the PBBans MBI, but it seems as though it wasn't actually that person who was hacking.
Someone will only show up on the MPi if they have played on a server that streams to PBBans, which not all servers do. Or, they might have a ban on another site and that might make them show up.
Correct me if im wrong.
