They could grab a mob and park it next to your group then break the charm and the mob will attack the group. I am sure it is against the rules but it happens. At least that's what I have heard people do to bots 
I don't know if it is still possible to do this but I think so.
It can be made to work like that if one of the target group members attacks the mob accidentally, but by default the mob would attack the player than charmed it in the first place (a hate generating action). Actually managed to kill a bot during a scripted play session once doing something similar to this. It was a wizard standing on a rock in TT in the middle of the forward group of blood-bloom mobs on the main island. They would target a bloom, nuke it with a specific rotating set of spell casts, then await another mob to enter their casting range. Auto-target. Rinse, repeat. The bot was surrounded by chests of all shapes and size and bodies that just rotted. I'd gather up a bunch of nearby mobs and run into his range and he'd helpfully nuke them all for me. Eventually we confirmed the toon was running on a script. I flew out to Breeding Grounds and charmed one of the big ^^^ wyrms over there and brought him back to the main island as my pet. I brought him near the wizard who was auto-nuking another blood-bloom. I broke charm and immediately stunned and rooted the wyrm which made him "my" encounter and had him aggro on me. I backed off while the angry wyrm stood there, stuck. Sure enough, when the wizard finished off the blood-bloom he immediately detected my wyrm (a targettable NPC) in his casting range and let fly with the nukes. I broke root and the wyrm promptly ate him. Made me wish I had FRAPS running at the time. I recharmed the wyrm and politely dropped him back off on his home island.
