According the Wikipedia, Suprnova shutdown due to legal threats, but never was taken to court. Basically, they just caved to the pressure. On the other hand, ThePirateBay has survived police raids and criminal proceedings.
Aside from that, it doesn't sound like SuprNova's setup was quite as intricate as this. I think that the post above was suggesting that the "caching border router + encrypted VPN" setup was what SuprNova used, but that's not everything that ThePirateBay seems to be using. Also, ThePirateBay only has to host magnet links, which didn't exist (IIRC) back when SuprNova was active. SuprNova had to host all of the .torrent files.
Indeed, Suprnova shutdown due to legal proceedings. Real jailtime is now coming to Piratebay founders, they are even on record as begging for reduced jailtime, after the verdict.
It's simple: the exist node in both Tor and Piratebay has all the legal exposure. That server/caching router/proxy could become impossible to host anywhere. Move it to USA? Expect 1 hour of uptime:-) Russia? Expect 10seconds page load times.
Any experience hosting people out there? Are Sweden and The Netherlands the only few-questions-asked options on town?
That's great news! Hopefully you found the demo fairly intuitive. We're constantly working on making the interface easier to use.
Right now we're definitely in a demo / beta stage where we intend to develop features on a request basis from our users. However, we agree with you entirely that some core features and a redesign is required to really make the steps more clear. I look forward to hearing more of your feedback in the future! Please stay in touch Grepsy and thank you for your interest! :o)
