What exactly does [Detected] mean?

So I've been lurking around these forums for a while now, and I'm really confused as to what "Detected" means. I was able to bind commands with ease (figured it out by myself), and they work, but I'm scared to actually use them. When people say detected, do they mean that everytime I use the commands, Nexon finds out about it or what? I never get any "Unauthorized Program Detected" messages in-game, but I'm still iffy about using the hacks.

So, could anyone care to explain what it means?

It means ur method of hacking is known to nexon, not that they caught u red handed and gonna ban u.

N uwill get banned....... in 10 years.. also yea they no n u shouldnt be doing it
