> If you run a web service and would like to provide high-security anonymous access, consider running an Exit Enclave -- a Tor exit configured to exit only to your site. If Tor detects that your exit and your site share an IP address, it will automatically extend the normally 3-hop circuit to your node, and the traffic will exit the Tor network on your machine rather than an arbitrary node (which could be malicious).

For what it's worth, DuckDuckGo has done this for the past 4 years[0].

I think StartPage is still the default for the Tor browser bundle, but I'm not sure if they have an exit enclave as well.
