Anyone with a return address and big cash flows is ultimately a slave to the civil court system, with all of its inherent flaws (such as claims without merit being able to cost you thousands of dollars that you cannot recoup).

It is in the best interest of large hosting companies, datacenters, and UGC sites to shy away from anything that remotely smells of liability because the costs can instantly far exceed the revenues from small customers due to the flaws of the US legal system.

Many other civil systems use a “loser pays” model for funding lawyers, but if you get sued in the US and win, you still have to pay for your own lawyers unless you countersue (and your opponent is collectible). This opens up a very obvious denial of service attack.
