Hook Point Scan Hit

C3PO is not working on any other PRIVATE SERVERS anymore!
C3PO is working on legit battle.net and D2X2 realms only

You don't, he placed those messages there to cover your whole screen to as a part of it not being supported for other private servers. You either use BNet, or D2X2 server. Honestly I suggest D2X2 server, just wish it had a server in the US to make ping better lol.

More exactly speaking, other private servers use their own modifications on server side such as Warden-like memory scanning as you can see above.
C3PO is also highly modified client-side program, so it may not be compatible with those private servers.
