ELI5: How sites like The Pirate Bay are illegal but find ways to stay up and even fight the cases brought against them?

The reason is that they do not host illegal files. They index them which puts them in the same grey area as search engines like Google and Bing. In fact, the pirate bay doesn't even host the torrent files, they provide magnet links.

 When they fail to respond to DMCA and other copyright takedown requests is when torrent sites get in hot water.
