"Though I'm not familiar with thttpd or savant, after briefly looking them over they appear to be http servers just like apache or nginx."

Not your parent, but it wouldn't surprise me to learn that "dark web sites" are using thttpd ... it's a very simple, lightweight, dependable web server. The major downside - the lack of SSL - is perhaps not an issue as you are running over an encrypted channel anyway.

If I just needed to throw something up - perhaps on a remote or throwaway host - thttpd would certainly be my first choice.

Also, thttpd[0] is fast, doesn't fork, and is resistant to DoS attacks. The downside is that it's no longer in many repositories, and it can be a pain to compile.
