I usually look for hackers both in my team and in the opposing team. I can be wrong but usually I think it for example from the vac ban or I see it in many comments where it is said that someone hacks. for who i might have kicked by mistake i apologize but given the hard moment for tf2 well it's easy to go wrong
Seriusly never cheated and usualy kick cheater but if someone tink other ting i dont know what you want
