i have the same problem. you cant necessarily stop it but you can get around them. I personally use proxy site's.If you want to get around blocked sites(myspace,facebook,etc) then proxy is your friend. http:/www.radiofairy.com is one of the best proxy out there. If you want a larger variety of proxy sites visit http:/www.proxy.org.I hoped this helped!
