fix(honeypot): remove DoS vector (#1581)

Using the User-Agent as a filtering vector for the honeypot maze was a
decent idea, however in practice it can become a DoS vector by a
malicious client adding a lot of points to Google Chrome's User-Agent
string. In practice it also seems that the worst offenders use vanilla
Google Chrome User-Agent strings as well, meaning that this backfires
horribly.

Gotta crack a few eggs to make omlettes.

Closes: #1580
