If you cheat online in an online game with Steams anti cheat system, also called VAC. You will receive a VAC ban.
Meaning you are banned from all VAC servers, you are still play on Steam games just not VAC servers. Like being banned from Arma on Battleye, you must play in the server where you get the cheaters, you know.
Get around them? Ermm, Cheathappens do not make trainers or cheats for online games, they are made and to be used responsibly in a single player game, nothing else.
If you use one and get banned, it is your fault, not Cheathappens.
I have been using Cheathappens Trainers for over 5 years and never ever had a ban of any sort, I have never used a trainer during an online play session, once I twice I might have accidentally, but I was in a private room.
For more information on what VAC actually is, read here:
LinkThat should hopefully help you with information.
Sorry but I doubt Cheathappens will help you with cheating on any lines to do with a multiplayer game...
