Why is there no Limit for how many times you Vote. I read a post saying somone has voted 200 times for Wagner. Is that really fair?

Yes.

(but if it were for any other contestant, that would be outrageous.)

There's no limit because above all else (the emotional well being of those taking part, fairness, etc) the show is about making money

Because of revenue.

Must have a hefty phone bill

LOL!!
