Thank you. Gmail must not be like our fellow HN users we see here, quoting a couple:

  “I'm tiny and only run little personal stuff. I just block vast IP address blocks.”

  “Apologies. :( Since you say you've never visited the website before, then that means you're either in one of the countries or in one of the residential IP ranges that I've had to block.”

Although Google isn’t afraid to completely block iCloud private relay from Google scholar. Other sites may reject the first iCloud private relay visit, then reopen site in new tab and often automatically assigns new unblocked IP. Anyway, I would’ve thought it’s an acceptable cost from e.g. Google’s perspective to block ranges that did something bad once in spite of collateral damage.
