I would reject that assertion, because it seems to tie a bunch of disparate issues in order to summarily "other" them. It probably makes for reassuring business metrics that are ultimately detached from reality. I'm sure my own browsing patterns are often miscatergorized into a bin of "look at how many bad guys we stopped", ultimately misleading businesses.

Please describe one specific trend/activity you're referencing, where an automated user agent specifically facilitates fraud, beyond merely facilitating users that just so happen to have fraudulent intent. Situations where augmented user agents are claimed to be prohibited via bullshit terms of service do not count.
