If I was going to boycott anything it wouldn't be the gambling ban personally. There to many shopaholics who wouldn't be able to stop buying to get it to work. Personally at this point I won't be spending any more real cash on anything other then premium and tier fees because I am annoyed with how they have changed the billing. I am annoyed with current SL economy and how things work at this point so I amr refusing to buy anything more from anyone especially land. If I sold out I would at this point have lost over 500 usd. I am just focusing on supporting things in SL I appreciate ignoring the rest.
Gambling has never really provided me anything except lighter wallet.
