They won't last long. Lawyer that could help them to win the case doesn't exist. I mean seriously, it's more than obvious that they're encouraging people to share copyrighted files.
File Hosts are always using the same old scheme, "Share photos, documents, school projects, with other students and your family". It worked for RapidShare, and it still works. You won't see anyone from RapidShare on forums which are mainly Webmaster oriented. You won't see them offering money in exchange of uploading. Simply, they're here for good. While file hosts like FileServe, Oron, FileSonic, are here only to make a quick profit.
People aren't stupid, if FileServe was against sharing of copyrighted files, their representative wouldn't be on WJunction. They wouldn't be talking about RapidLeech. Like yeah, normal person would use RapidLeech, to download "photos from vacation."
They wouldn't be on forums full of people from third world countries, who use the Internet only for Facebook and RapidLeech (or sBorg).
FileSonic, FileServe, Oron, all of them are probably (more like 100%) registered on a fake person. Even if the government manages to seize their servers, or to get ISP's to block their IP's. Guys who were managing them would have enough money to start a legit business, and move to some country, where no one would know who they are.
