For me, disliking a band because of its fans is rather silly, since a band has no direct control over fan behavior in most cases. Of course, I'll be deeply relieved to find fans of my favorite bands having enough sense to conduct themselves in a proper manner. But even if they don't, it is tangential to my enjoyment/distaste of the band's music, since I would rather focus on evaluating the band on its own terms. Not doing so is simply unfair. Granted, this might be a bit difficult for people who are particularly steeped in "fan communities" - but I'm not, so I shall not comment on that.
On the other hand, I don't particularly find anything wrong with having 2 pages on a band's new look, mainly because aesthetics constitute a part of the overall experience of any vk band. I would rather have bands invest some time/effort to pay some attention to their own presentation than disregarding them completely. So having fans who are sensitive to those stuff is a good thing (even as aesthetics may not be my primary criterion for judging if a band is "good").
