WeMod does not condone cheating in multiplayer nor does it provide the tools to do so.
Trainers from anywhere on the internet are only designed to work in single-player offline games. Aside from that, major game developers are aggressively suing producers of online hacks.
On the rare occasion trainers work in online modes due to oversights by the game developers, then the chances are you’ll be flagged by a bot to be banned or shadow banned in the game’s next ban wave. Unless you’re already shadow banned (the point of shadow bans is that you don’t realise you’re banned, because you’re only playing against other shadow banned cheaters).
