Sure, but the truth is they had no choice but to shut down after their life was made ever increasingly harder running a torrent website in a country where authorities were passing stricter anti-piracy laws and started going harder after pirates, after the US and the big movie and games studios started putting pressure on Bulgaria. Same thing happened in Romania a couple of years earlier where the original domain of the Filelist torrent tracker was seized. Are you ok with loosing sleep over the risk of going to prison or going bankrupt fighting trillion dollar movie studios in court for your famous torrent tracker side-project?

Check US Special 301 report, Romania and Bulgaria were on the US naughty list, and had travel warnings issued for them, despite being safer countries than the US and also important NATO members in the region, with the reason given in that report that US entertainment piracy is rampant in the region lol.

The big US movie studios cand leverage the US gov influence to put pressure on other countries to crack down on piracy. That's how strong they are. I remember the good ol' days in Romania when piracy was absolutely rampant that you would see ads in the city about ordering CDs and DVDs with quality pirated content through the mail, then we joined NATO, then suddenly anti-piracy laws became way stricter. You gotta play by Uncle Sams's rules if you join his playpen.
