Since I'm only starting to learn how to create cheats, for now I'm active in the TK'ing aspect of "heckling."
Does anybody else get a kick out of forcing other players to TK you enough times to get kicked (or even banned) from the server? What I do is shoot someone in the leg, enough to make them lose some health, but not enough to die. They immediately get pissed off and retaliate by emptying a clip into me. Do it enough times and the next thing they know, they're kicked off by the server!
