Spiffing mate, honest to god he's not hacking as Warriorrr only gets this problem occasionally and last night after a reboot the problem went away completely. A few nights ago, I got the exact same problem, well almost.... Veenstra said I was moving way too fast and apparently my Demoman model was constantly looking straight up, many people called me a cheat and left but i didn't have a clue because i don't cheat.... honestly, whats the point in cheating?
The problem isn't really a 'Speed Hack', its more Lag related. I found this last night:
"Laghacking" is basically fiddling with your rates (updaterate, cmdrate, etc) to limit the connection between your client and the server, which causes your hitboxes to trail and makes you very hard to hit.
In other games its called, "ghosting", because you appear one place and then another. It's not really an issue in TF2 (yet)Mine and Warriorrr's rate, updaterate, cmdrate are the same they've always been.
I also have some demos of Warriorrr doing this in the past week as it was extremely frustrating and rather pointless playing against him. At least now he has seen them so understands why people are calling him a cheat!
I've only had this problem on GTFO Lazy

EDIT: I have a demo of Warriorrr on Multiplay Lazy last night and he's doing the same thing, although it's not quite as noticeable when he's on the same team
