It's very simple to stop opera site-check from accessing your private information.
Get a new browser
Get a network filter eg. Little Snitch (mac) or Antivirus eg. (AVG) or directly edit your firewall settings and add http://sitecheck2.opera.com to deny connections, that way everytime sitecheck attempts to access your browsing, privacy... It fails.
NO it's not like as easy.
if you block the fucking sitecheck domain in little snitch, opera isn't really useable anymore!!!!!!
it's unbelievable and without words......
there's really NO single browser out there (for os x), who is not overload with tons of plugin shit, animation shit, extension shit etc. plus every developer thoughts, every chimpanzees needs the option to work with their software.
if the user isn't able to understand a pc, internet and the traffic, then it's their pitch!
or why do the fuck we need a driving test???????
if not, there'll be millions of killed people on the streets EVERY day, cause the mass is dumb and will be dumb if they doesn't want to learn!!!
that's what life is for, among other things off course
