Yes, that's true, Lord of the rings... I had few monthes ago that sort of trouble with Free... all of a soudain, the search went almost blank, some files somehow continued to download and upload, but not terribly fast... and then it became worse, till finally LimeWire was meandering trying to connect from starting com to sometime fair com, but never turbo or even excellent or good (and indicating the presence of a firewall). As for eDonkey, it couldnt anymore connect to the servers, and only, sometimes on overnet... the only app to go through that machination was Ants, but being crypted from beginning to end, mixed up with other flows, and using other channels, I think it never was detected as a client for P2P... I such cases, I believe the only solution is to leave that sort of ISP (When it is proven) and also to tell him why, since, if enough people are doing so, it may make him think twice before doing it...
