Don't wanna send you down a rabbit hole, but this server can detect the aim-assistance mod.

The server does not ban you when it detects your use. I assume this is because the developer does not have 100% confidence it will only detect people using aim-assistance mods. You might get banned if you get kicked multiple times due to detection. Here is the server IP if you are interested: ip.txt
I attached it so this issue can't be found by people searching about the server.

The aim assistance can be customized, you can try to decrease some of its settings. There's nothing more I can do about it on my side to prevent it from being detected sadly.
