[SOLVED]How to detect a hacker

Jello,

Ive been playing ava for 3 weeks nao, and I think the game is pretty fun, but now that ive leveld to blue rank and i cant play on the beginners channel(where i really loved it, it was uber fun, very random who was first or who won, allways nuff pplz and nuff kills) and now that im on the publick channel its really frustrating with either how much my skill has gone down, or how much everyone is high skilled. And theres some weird things ive encountered with players too... Like, is someone hacking, if its escort, and the game starts, and the dude is like suddenly behind me after 5 seconds ? is that like a speedhack, or lagg ?? do speedhacks even exist in ava? or sometimes, im shooting this guy in the head, and his head starts moving around like crazy, like its dodgin bullets in the matrix, not all the time but it happen once or twice while i tried to kill him, which i failed ofc(its like he turns it on or off, he had like 47:12 score at the end, maybe it was just lagg but still).

Or a couple of times it happened i tried to kill the guy and shoot him, and he kept flying up in the air and then he was down again, and flew up again and then down a gain...and im seriously suspicious about the scores, some blue or green ranks or red ranks play and have 53:6 score at the end of escort scorpion, and they dont sit at the rpg box and shoot rpgs or repair the tank, they kill other players the whole time...

so it would be helpful if you could tell me how to recognise a hacker? also, if im host, is it possible to kick someone while mid-game without having to use the f7 voting system ? coz ive been kicked before and i didnt see anything on the lower middle part of my screen as in press f5 or f6 i just seen people typing f5 and then i got kicked, sometimes typing nothing...does the one who is getting kicked not see a vote has been cast against him ? or does it sometimes not show as a bug ?

sorry for all the newb questions, id just like to know how to spot a haxor :P

thanks

edit: oh and i just noticed it might've been better if i posted this in the help or general section
