Are all unlocker detected?

Is that trou that all the Ulocker are detected? I only need all weapons lvl 31 and 15 classes. Is that banable?

So when i use one i get 100% banned or is that the risk to get baned like always?

Steam scans for the names, etc. of processes that write to the memory of the game. So if it's been released a while now, you chance of being banned increases. ( Unless it supports dynamic names etc. )
