i talked to some technical staff of globe,pldt and bayantel regarding the blocking of p2p or any torrent sites. they are not actually blocking it but more of filtering it. torrents and p2p eats up a lot of their bandwidth and as we know most isp assign a certain bandwidth within an area i.e. street, villlage etc. etc. and these bandwidth are being shared among the subscribers within the are thus comes their official guarantee on their public ads the phrase "with speed UPTO "X" MBPS". they usually do the filtering on areas that are near congestion so that everyone can have a fair share of the bandwidth. swerte ang mga non congested area since they mostly do not do any filtering or etc.
