This is the best excuse for instituting a penalty of some sort for agreeing to kick someone who isn't linkdead. The devs have already said that folks who frequently initiate kick votes are eventually punished by having to wait longer and longer before they can initiate another vote, but mindlessly agreeing to go along is just as bad.

Perhaps there should be a limit to the number of times you can kick anyone in a week.

Been there. Had a number of people leave just after Madness was pulled. So the gaps were filled but the new raiders couldn't zone in as the encounter was in progress. So, after the wipe, the vocal few broadcasted "HEALER X DID NOTHING ON RECOUNT, KICK HIM" and even though he said many times the reason why and people defended him, he was kicked. I know that people actually run without raid chat showing coz they don't want to read the crap that people whine about. It really comes down to the fact that a lot of people just don't care and just want their loot/vp quicker.

I wish there was an official way to rate players in game. Gain reputation. If you see a bad player or someone with bad behaviour, rate them bad and write your reasons for it.
If you get enough bad rep, you could be locked out of tools like vote kick or could get longer queues as reward for being an asshat. It could also appear in their Bnet profiles with a nice RSS feed of how people rate you. I bet people will start behaving better just to maintain a good rep. Or maybe something like the rep system in Xbox Live. I know, a system like that could be abused too. But I think Blizzard is capable enough to implement something that works.

Personally I'd like to see something in Raid Finder where a person who initiates a kick that fails gets kicked themselves, as most the time the person who initiates kicks that could fail would not be missed in my short experience there.

Speaking of exploiting the system, I was in LFR on my Disc Priest, pulling my weight and got booted after downing Spine but after rolling on the loot by the RL and his friend who were the only ones with Assistant privileges. This was after they had been spamming the Ready Check button the entire raid (before, during and after pulls). I stopped clicking on anything and playing along which I assume is why I got booted as I wasn't saying anything in raid chat or being called out for anything either. There needs to better ways to prevent and RL from ninjaing the raid and getting random players loot locked for their own enjoyment.
