A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

Captchas pretty much worthless. They're easily bypassed for basically free. You're better off putting your instance behind Cloudflare with their captcha
Okay, so do you mind explaining why the servers onboarding the most spam users are the ones without Captchas?
If they are so ineffective, why are they effective now?
Invisible captchas are about as useful as graphical ones and are significantly less annoying to the end user
I'm mixed about this. When applied correctly, a graphical captcha will let zero bots in, at the expense of false positives and frustrated users. On the other hand, invisible / proof-of-work captchas will let a fraction of the bots in (blocking majority but not all bots, by design), while providing better experience for legitimate users. Pick your poison basically.
Absolutely untrue. There are services that will solve captchas for you for hundredths of a penny. It's essentially free.
