I guess people will just have to use one of the many other BitTorrent search sites with similar features and torrent coverage. This sucks for the IsoHunt folks, but for the people actually sharing files, it's more of an inconvenience than a crippling blow.
This could be bad news for me since I've been one of the people involved in working on the "lite" version of IsoHunt. At the same time though, I'm pretty excited, since I could be coming into a lot of free time to work on my startups.
