I know that,but i was thinking to use ip as proxy somehow,to act like i'm visiting facebook,i know everything is on isp side,but there must be the way to send a query to isp that looks like facebook,and bypass that speed limit for other sites i have right now(i tried a few combinations for proxy,but so far without success)...
I also used web sniffer to find out which facebook ip is on my isp "White list",and i found that ip,and for now that is all progress i have made...
