Ask HN: Am I being advertised an ARG via user agent logs? (opens in new tab)

I'm here looking through logs on my unnamed reverse proxy and CDN service. The crawler bot swarm has been hitting my PHP application like I've upset them so I'm seeing which weird user agent strings are being allowed to connect. There's "Sogou" and "meta-webindexer" and a small number of requests from "SleepBot/1.0"
