Autocheat, if I call it right, is an automated system which detects any not wanted actions during gaming.
For example, yesterday I was docked on planet sprague with my BAF sabre, when I wanted to change few of my guns.. When I unmounted several of them, and tried to buy one flashpoint, I experienced heavy lag, and the server kicked me. Tried to login like 3 times, when I can finally jump into my ship. After some research, I find out that the lag I experienced, made an unknown copy of the gun I unmounted, and the anticheat detected that I just made 2 weapons from only one. When I came back, that gun went away.
It's a system to keep the players from having unfair advantage.
Also, after some youtube videos, I saw a guy who launched torrent, started downloading, while buying weapons for his Defender.. he cloned about 16 guns, making an extreme punch on a succesful hit. Anyway, it's fixed in discovery, but if you are bored in the vanilla, or real freelancer campaign, you can try it out there, since no one fixed it in the vanilla fl.
Um, to be more correct, it is called automatic anti-cheat system. (Autocheat means you cheat automatically, or something like that, which couls be confusing.)
Anyway, I saw you logging in then get kicked by the anti-cheat a few times. I think it is time to ask an Admin to look into this matter. I think they can check why did the anti-cheat kicked you, which might draw you closer to a solution.
