Huh, I get a lot of traffic from Amazonbot (relative to humans) and try as I might, it would get stuck in a tarpit of no creation because it would sit there and keep blasting every variation of my recent pages because Mediawiki lists many links. I have them appropriately nofollow and warning the bot not to waste its time with robots.txt but it just goes and sticks itself on nonsense internal pages.
The traffic isn't a problem. I've got Cloudflare in front and the machine itself is relatively overpowered, and downtime isn't critical. But I'd just like the thing to be able to spider me properly. Someone did point out to me that maybe I wasn't receiving actual Amazonbot but some other spider: https://news.ycombinator.com/item?id=46352723
