SO MANY THINGS HAVE BEEN STARTED ABOUT THIS
I voted no, because then the power will be abused, even if you dont think it will, IT WILL BE ABUSED.
If it were only if the member was WRONGLY BANNED, which you didnt state here, you just said votebanned, then sure, ban the guy.
Being in a clan doesnt mean you can break server rules, even though I've seen people do that and then someone else (YES IN ASM) just says "ah theyre in asm theyre cool since they only do it when they leave its ok"... but someone who kills everyone then leaves ONCE that ISNT in ASM gets banned...
its gay.
