Seriously, he does have on record tweets asking how to get "overseas" votes. He also offered prizes/services for votes, yes, Ed's family did too, but not to the extent and took it down. I am not supporting Leesa whoever here, but clearly rules state voting only in AU. This is a legal document from Channel 9 that will stand up in a court of law. There are tweets to the voting lines from whoever One Direction is saying they will talk to you and he retweeted those. Hell, I was willing to send for Tim at one point, right or wrong! Last year I could vote via FB, but this year not so. It has been in your media even.
I can from the US here pull Paypal information as to how we could have voted for Tahan and we are fanatical BB Fans as well. The Phrase may not be good for him, but technically if he solicited votes illegally it is a "scam". A fraudulent business scheme.
I liked Tahan. If not Tim I wanted her to win. If he was damaged then I don't see his sponsors 30 days after letting him race. In fact Tahan is bringing them new publicity IMO.
