Note-worthy from the article (as some commentators suggested blocking them).

"If you try to rate-limit them, they’ll just switch to other IPs all the time. If you try to block them by User Agent string, they’ll just switch to a non-bot UA string (no, really). This is literally a DDoS on the entire internet."

I instigated `user-agent`-based rate limiting for exactly this reason, exactly this case.

These bots were crushing our search infrastructure (which is tightly coupled to our front end).
