Somewhat Threatening Sniper
https://mega.nz/#!StxgSQbK!_6HSPPZKyne8cmu8JmGqZMYS13ugPcMIEQpdhUpaeyg - demo file two

12.5k - User is blatantly aimbotting as Sniper. Shots automatically lock on to the boss.

106k - Even more blatant aim-lock. He also seems to look through those leaves despite not seeing the boss prior (right after a massive flick), although that could be argued away as a pre-aim.

User was also spamming racial & homophobic slurs and just being a jerk in general. He also reported LimpToast for cheating, which was certainly false. Limp is a long-time veteran in the Skial community and has the respect of myself and many other players there.

Additionally, at 112k on demo file one, user "Random Fucking White Guy | Tf2h" ([U:1:462023396]) looks to be aim-locking as well. He seems far less blatant though, might've just been bugging but I thought it was worth pointing out.
