Well in that case I guess it not so clear.But definitely a person who joins an online gambling site expects a ceratin degree of freedom to play with accounts and such.
Who doasent have several accounts on various websites?
My opinion is , if he is profited and brake rules then take his money.If he lost money atleast return some of it.
Bonus abuse is a big no-go for all online casinos. It's called a Welcome Bonus for a reason. They welcome you as a person the first time you arrive. They give you a 1st deposit bonus only the first time you deposit. A 2nd deposit bonus when you deposit a second time, etc. You can't be welcomed 10 times and receive 10 1st deposit bonuses. That's cheating and should be punished. A slap on the wrist isn't enough. That's just an invitation to try it again. Harsher punishments are needed.
Compare it to what happens on the streets.
If you drive a red light 100 km/h and the police give you a $20 ticket, you aren't going to take it seriously. When you lose your license for a few months and get a hefty fine, you'll be more careful next time.
Well depends if the speed limit is over 100 km/h in that area. Then its just a red light not speeding.
