As soon as the ball is touched you can touch receivers . It doesn ' t matter who touches it in air . You ' re used to seeing receivers get smashed the second they touch the ball . Same premise . <| sep |> I hear stories of people hacking hackproofed and protected clients all the time , as well as patching around network encryption schemes . I think one way to help mitigate cheating is to have authoritative servers which check all client messages for validity and contextual validity . This may also involve statistical analysis of gameplay to determine if some players may be bots play for excessive periods without fatigue or reduced reaction times , etc . . It ' s probably better to assume all messages coming into your servers are from bots and hacked clients and to treat them accordingly . While it may be possible to reduce clientside mods with some of the methods you mentioned , keep in mind that some determined hackers are extremely clever and may be even far more clever than those designing the proposed solutions . They can also share their methods across the net to crowdsource better hacking techniques .
