It's really too aggressive. Personally I have not yet been able to open _any_ cvsweb links without getting caught by it, in straightforward situations when e.g. someone sends a direct link to a diff.
Imagine opening an innocent-looking cvsweb link on your phone that someone just sent you, as you are trying to put your kid to sleep ... and then getting caught by the redirect because ... goodness knows why? I never tweaked any browser settings nor fiddled with headers, so I concluded it just hates my ISP. Totally appreciate the need for self-defense from scrapers and I am really glad something is in place, but I (and I guess my now ever slightly more sleep-deprived 6-year-old) would greatly appreciate finding different anti-scraper tactics. Like send them to an iocaine instance or something. Scrapers running headless on some VPS are not too annoyed by the popups and videos and whatnot, this only annoys actual humans trying to access the site who get caught by the filters for whatever undiscernible reason.
