How are you so sure that alliance are able to remove people from battlegrounds? Alliance and horde are truly no different when it comes to exploits or people you meet (not community wise), so what is stopping horde from doing the same thing? Don't even say something like because hordes are more mature and respectable, hackers and exploiters don't care what side they are on and will join either faction.
There has been some bug going around about the whole or nearly the whole battleground crashing for both factions and even in PvE scenarios if you receive a wow error ; chances are everyone else in the group received one as well (not 100% of the time, but at a decent portion).
What are the chances of nearly EVERY if not every alliance you meet in a battleground causing you to crash or disconnect? If you want to get it solved, yes write down every name and see who comes up more often, but even that has a possibility of not proving anything.

I am not trying to sound like I am being pissy, mean or ranting, but there are more reasons that would disprove alliance constantly crashing you than approving it.
