The internal i use has been ud for 4 years and counting its "invite only" but has 6k registered nowadays, but yes externals are generally a little safer
The internals being detected currently aren't actually being detected anyways, aw and ot got detected for certain exploits that they had annouced were unsafe yet users did not listen, not the cheats themself. I personally prefer to use internals because they are more feature rich and the games free so on the off chance you actually do get banned you can just make another account. Most people just semirage in mm anyways even with prime and high trust factor
