I work at a Swiss hosting company - few corporate entities from the US go as far as getting a court-order from a Swiss judge (which we require before we do anything).
We get tons of bogus "Hi, I work for
We all tell them to come back when they've got a court-order signed by a Swiss judge. Registered mail.
But of course, unless you also live in Switzerland, the lawyers will eventually just target you directly.
It helps to filter out all the "noise", though - I admit.
Additionally, you've got to choose a hosting-provider that has no US ties - else they just go via the US HQ and then you're back at square one...
