Forget esoteric areas, I'm an average American guy who gets them running from a residential IP or cell IP. It even happens semi-frequently on my iPhone which is insane. I guess I must have "bot-like" behavior in my browsing, even from a cell.

I noticed that Google happily puts you on its shitlist as soon as you use any advanced parameters on your searches, such as “filetype:” or “inurl:” or “site:”.

This probably has something to do with it. I probably tend to move faster than average and am "bot-like" in that I sort of "scrape": search for something and quickly open all relevant tabs to review, page through them, search again. If while I'm going through I have something else I'd like to find, I'll fire up yet another tab and pop open all relevant tabs from that. Etc.
