Sure, but even if you assumed Tor was perfectly secure, there are still other ways of being exposed (like someone causing your web server to issue a network request to a host they control).
No matter one's assumptions, it makes no sense to me that someone would register a VPS with their own information when it's pretty trivial to do so anonymously. Especially if you're running an illegal content hosting empire.
DPR's mistakes at least made sense to me; they're something anyone could have overlooked, even if they were still very naive mistakes. But I doubt DPR used his personal information when paying for servers. That's well beyond "unrealized mistake" into pure incomprehensibility.
They supposedly caught on to him by connecting an email address associated with DPR to his real-world identity. Wouldn't surprise me if that was an ex post facto lie concocted to conceal the true method, though.
