So today i join one of my favourite servers 2fort with 32 playcap. I wanted to work on my engie skills for the scout pack. Anyway I joined RED team, just as i place my sentry in the courtyard a red demo walks pass so my reflex is to wrench him. I hit him and blood flies off him. So he's not my team and he's not a spy in disguise(cos they don't lose blood on been hit) so who the heck was he? Meet the Unassigned! Anyway this red guy started stickying my sentry and blew it up! then he did the some to the other red engie nearby. By this point i'm sure he's hostile so i chase attacking with my shottie. demo>engie so i retreat to spawn room and go back after him, he's shotting red sticky that flash blue as they touch the ground then go back to red, also they can kill me. soon i shot him dead, two things happen. one: on death he turns blu, and the 'kill text' in the top right has his name in white. I admit by this point I'm posting [box]Scout1 is a hacker! but he isn't. Valve have for whatever reason have made this little gem and left it in the game for anyone to exploit. cheating is giving your self an unfair advantage so this guy was in my eyes was cheating. I started screen capping and alt tabbing. however after 4 times TF2 crashed. So i started Fraps (a PrtScn and motion cap app) and rejoined the server BTW default Fraps PrtScn is F10 so TF2 disappeared. after working out what the problem was i changed it to F9 (also the default video capture key) so after fixing all that no one was talking about hacking, half the server was doing it, below is a series of screen shots piled together to showcase this 'feature' that Valve made, I just want them to stop all users but STEAM_3,4:Y:Z from doing it.
