I'm not sure what hosting service would ever do something like that, money is king and if they just drop sites because someone tells them to they would go broke. I would be more than happy to give you the names of several hosting services that would never, EVER drop a site without a court order. If DPP is using a foreign hosting service, I'm sure it's waaaaay more money and since it could hosted with unlimited bandwith for less than $5 a month here it's worth fighting for. Also PP are bullies that need to see that just because they talk a big game, not everyone is afraid of their idle threats.
It's called a DMCA Takedown Notice (and it is, essentially, a court order. I'm not 100% sure if it's _issued_ by a court/judge, or if it's the first step handled by a lawyer before going to court). You have to have a lawyer fill out the DMCA takedown notice paperwork, and send it along with a cease-and-desist order to the hosting provider claiming that the website is violating your copyrighted content. This is exactly what PP did to the original hosting provider of DPP causing them to shut down the account. Hosting providers will _ALWAYS_ honor a DMCA takedown notice (they may be required to by law, but if not, they will be held liable for any illegal content left up on the internet for any time after they receive the takedown notice. If it's a frivolous claim (or even a 'legit' one that the site owner chooses to fight in court), and the court determines that the DMCA takedown notice is in error, the host will put the site back up and can likely ignore future similar notices. If the claim is found to be legit in court, then the site owner is responsible for the legal issues, but if the host doesn't take it down immediately, they can also be sued for damages.
As you said, money is king. No hosting provider will risk a potentially 5+ figure lawsuit just to keep one $10/month account active.
Yes, PP is pretty stupid for even making the threat because if it goes to court, you can bet Disney will step in and just tell everyone to remove every single reference to their copyrighted property. That would effectively kill PP and DPP on one move and it would all be over. But they did it, so Ethan moved the site to a country that doesn't care about DMCA takedown notices...
The DMCA takedown notice can be completely false, but it will serve it's purpose: The hosting provider will take down the site until the legality of the notice can be determined. That means the owner of the site would have to hire a lawyer and prove he's doing nothing wrong. In the mean time, the site is down. As mentioned before, it's just a bully tactic (unless the site really is infringing on a copyright, but since PP doesn't own sole copyright on anything on their site, and their terms of service at the time DPP started granted free use of the entire database to anyone that wanted it, there was no infringement. But Ethan would have to go to court to prove that.) You notice he's not afraid of them as he's still running the site. If PP had a legit claim, they'd actually just take him to court. But they'd first have to prove _THEY_ own the copyright to everything on their site (i.e., all the photos with DisneyStore.com watermarks, all the descriptions that are copied word-for-word from Disney websites, anything any user posted, etc...), then they'd have to prove Ethan took the information in a matter that was against their terms of service at the time he started DPP (at that time, the TOS said anyone could copy the database. The TOS has been changed since DPP went live...)
Ask any of the hosting services you are thinking of if they would ignore a DMCA Takedown notice. I bet you won't find one, based in the US at least.
