Seeing more of this still-rude bot lately, two to three times/week on some sites, apparently hitting IPs in sequence. Alas, it's still:
- using multiple UAs;
- going for root or an Apache server (not web directory) file;
- log-spamming;
- only from AWS (in recent years), and, of course...
- not requesting robots.txt
