I've heard of that before where the ISP sees people uplding files & considers it as a server. You'd need to read your isp policies to see how it affects you. I don't know whether it will help but you could try setting up a proxy. (Some isp's also don't like proxies set up without their permission - read their policy.) For more info about proxies see: A Fix for those whose ISP's block Limewire pages 1 & 2 which has a link to alternative instructions.
