And I would've kicked him after he needed the first boss drop if he hadn't done anything. Worthless ninja looters need to die.
Unfortunately, unless they've changed it recently (I haven't even bothered pressing it while the timer is still up in a while), you're unable to kick someone within the first fifteen minutes, as the vote to kick is tied to the lockout timer. You also have a limit of one kick per run (this one I've read about, I have no idea if it's true as I've thankfully never felt the need to vote to kick twice in a run without deciding instead to just leave in the first place). AND they've recently added a "You cannot kick during combat or shortly after" feature to the button.
That last one I can understand, as I've heard there are groups that kick people after downing a boss who's dropped loot they want, and then ninjaing the loot that way, with the kicked person getting shafted and replaced. It's still annoying if the tank is part of the problem and he's chain pulling, meaning your options are ditching between pulls or living with the bad tank or hope you're far enough before the pull that he dies on his own. And sometimes, they just chain pull to get instance run over with, so by the time the option to kick bad dps is technically available, you just can't seem to get that vote to kick to trigger. That said, given the possibility of ninja looting this way, I really, really do understand the need for it.
The kick limit and the lockout timer tie-in, however, highly explain the high amount of AFKers that zone into an instance and then do jack-shit. Well no wonder there's so many of the douchebags showing up! Blizzard is now rewarding not just AFKing in Alterac Valley, they love rewarding AFKers in instances!
Go Blizzard!
The kick limit/lockout timer, not only helps afk'ing dps, however, it also helps jerkass tanks or healers with enough patience. One gnomer run on my rogue, the tank did some chain pulling at the start, then proceeded to jump to the bottom where elemental boss is, with a party message of 'follow me' after he jumped. One of the trogg pats aggro'ed on someone before all the rest of us followed as I heard the aggro sound while I was mid-jump, and suddenly as we're drinking/eating at the bottom, we get swamped by like 15-20 troggs and a bunch of the slimes.
The healer keeps -all- of us alive, with a few rough spots of close calls, but not a single death. The tank, however, goes look at his gear and spec, he's a disc priest, and has a bit of defense and strength on some gear (which is not exactly rare on a levelling toon before level 30), and declares him a PvP priest, and that unless he leaves, he will not move from that spot because he does not want to pay for repairs because of a 'shitty priest'. A 'shitty' priest that kept us alive through a seriously huge overpull. Right.
Only about 3 minutes since we started have passed, so there's still plenty of time on lockout timer. The healer refuses, pointing out that he kept us alive through that. Tank simply ignores him and starts throwing a leather ball at one of the dps and they just play with that. Eventually, I get tired of waiting, the tank had also ignored offers from me to pay his goddamn repair IF we wiped, and just leave even though the timer's almost up. I honestly wouldn't want to party with that tank anyway, though I imagine the poor priest got kicked once the timer was up and the tank got his way.
