Prelude: I develop a cloud service which could be described as dropbox meets torrents and as side effect it enables distribution of arbitrary content via magnet links. Certain amount of magnet links will be displayed on the main website (I will be able to remove them one-by-one or ban users but no more). I will not be able to avoid magnets without complete rework of overall project architecture and either way it will hurt overall performance badly, probably making service meaningless.

So my question is, what should I do, to avoid legal problems if my site in a nutshell is just a collection of magnet links? Privacy achieved via end-user encryption, so there is almost no access restrictions on the website. And anyway will help me any?

Will hosting in particular country help me?
