well I don't appreciate having my freedoms limited (to tweet, send a text message or make a phone call or whatever) because of betting. If I'm at a tournament, I'm a paying customer. Thousands of innocent tennis spectators who don't give a shit about betting have to be inconvenienced for what: 10 or 12 guys who might be these punters? It sucks.
Quoted for truth. I agree in all but the "paying customer" part. ITF tournaments don't generally charge an entrance fee. They're free. But other than that it is what you say. You re giving away a freedom just because of betting sites.
