When I first started out on twitter I hung around with the 'beyhive' and they seem to drag anyone (including Kelly/Michelle, basically anyone who isn't Bey) which I found over time is foolish. It made me get blocked by Rihanna but only Jessie for ATRL.
Lady Gaga, without question, but to be fair they wouldn't have been able to do that if she didn't already have ticks that were already starting to annoy me.
I'm starting to see some Beyonce fans can be as hyper but Beyonce's lack of internet usage to show her nature, bad or good, gives her a huge advantage. I only have the image she wants portrayed through regular media and it's a good image. Her fans attitude hasn't influenced my opinion of her yet and I'm trying to back away from communicating with Beyonce fans online so it doesn't really also hurt my opinion of her fans as much as it did with Gaga's.
