I've seen these guys twice (opening for WCAR last year, SILYMI 2011) and until right now I actually forgot that I've seen them more than once. Obviously they left a huge impression on me, haha. I used to love this genre I've just grown out of it, I guess. As a whole the genre has almost no evolution over the past couple of years.
The band was all over their social media sites promoting the poll. Someone in the original list thread posted a link to a Facebook post that had quite a few people saying they registered to vote for them 5 times. It's hardly a fool proof system, and if FOB had come back a week earlier they would have easily won.
So definitely not a legit win. Good for whoever these guys are for promoting themselves though.
