I don't really see how them changing the name to troll is a problem. If they change the name to something stupid then you just leave the group. I like this idea though because a lot of cool people (Sparky for example) have fan clubs and then get a name change. Sparky's fan club is still under the name Sparkyau even though thats not his name anymore. So it would be nice if it was possible to change the name of the group to match his new name.
