That is one out of potentially thousands. I run into people using speed hacks or auto-hit hacks almost every day. Combined with the 'huge' problem of each continent being controlled by one faction with 10% pop from others, I've basically stopped playing until they both fix the hacking problems and find a solution to the population issues.
Oh and lgFreiss, that is one of the more common 'hacks'. Combined with a speed hack it makes killing those people impossible. I used to only see them once in a while, now if I spend an hour online I'll encounter half a dozen.
