I’ve seen those puzzle piece captchas (common on crypto exchanges) that always say I completed the puzzle faster than 99% of users (even if I didn’t do the puzzle particularly fast). I presume those 99% are all bots attempting to hack into crypto wallets.
Here’s the thing about all search engines that aren’t Google (including the ones “based” on Google results). They all suck for regional results in many non-Latin languages.
