I got report from my server that there was some guy that did really fast laps and there was something odd with his driving, which I don't write here to prevent others getting ideas.

Where do you usually check these things and what is normally procedure handling these issues?

Send the replay to the Devs if you have one, or give them as much info as you can.

Can you check on LFSWorld to see if he is one of our resident Aliens ?

I would suggest that you send a PM and replay of any weird stuff to one of us moderators and not post anything about it on the forum. That way the devs get the info right away and you don't get a public scramble to find and exploit the possible cheat. I recall several licensed users being banned from various servers the last time an exploit was discovered and there was a general air of distrust online in races.

Thanks from quick answer.

Racer that reported this has not got replay also my server is in demo mode so there is not details of race in LFS World, however I got LFS Lapper running and I have racer name, which does not reveal much of anything from LFSWorld. He might been also demo racer.
I'm pretty sure he was not Alien as he did not got fast lap time but was fast driving a way with one possible can't be so fast.

Ok, thx from info Gunn, that sounds very reasonable.
