all you have to do is two things.
1, do not select a common torrent port for your torrent client
2. use encryption
ISP can't block, they will try to reduce the bandwidth on ports that are commonly used by torrent clients.
usually Internet users running torrent softwares eat a lot of bandwidth provided by the ISP(Usually 1/4). Its a common problem for all ISPs in the world.
But in SL, I don't think that it is the problem. internet is still new to sri lankan users, and most of them do not know about torrent. So the bandwith percentage for torrents should be still low.
But, instead of doing some upgrades, they are trying to get the advantage of limiting torrent. A cheap way.
SLT sux to the max. but still we have only slt for unlimited broadband. what to do
