Okay, I have a feeling that those voting 600+ times each night are wasting their time. Something tells me you can only vote once.
As I said before, if they know what time zone you're calling from, they recognize your phone. This is heavily audited. It's not some free online php poll script, this is a real thing that's tested.
Those who voted 700 times for Danielle last night, I didn't vote for her, of course, have to agree.
Additionally, if it was proven you can vote more than once - ANYONE could sue saying that they were not judged on talent, but by how fast their fans could press redial. It would be fraud on the part of the production company, as well.
I don't see how I could be wrong on this.
