Is it acceptable to be in two Xbox clans?

stick with your real friends bro, cause quite honestly the "professional" clan probably just wanted you in theres cause you kicked their asses, and they will probably never treat you the same way that you're friends treat you (i mean that in a good way) but on the way of "xbox socially acceptable to be in 2 clans?" for the same game, that's kind of a no-no, but for other games, like be in xDPCx for MW2, and then be in D4RK for Black Ops, thats perfectly fine.
