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.

Admins, we're about to have a really bad SPAM problem when Lemmy removes captcha support in v.0.18 - You ALL have a responsibility to communicate back to lemmy devs to try to stop it. (tucson.social)

Look, we can debate the proper and private way to do Captchas all day, but if we remove the existing implementation we will be plunged into a world of hurt.

I run tucson.social - a tiny instance with barely any users and I find myself really ticked off at other Admin's abdication of duty when it comes to engaging with the developers.

For all the Fediverse discussion on this, where are the github issue comments? Where is our attempt to convince the devs in this.

No, seriously WHERE ARE THEY?

Oh, you think that just because an "Issue" exists to bring back Captchas is the best you can do?

NO it is not the best we can do, we need to be applying some pressure to the developers here and that requires EVERYONE to do their part.

The Devs can't make Lemmy an awesome place for us if us admins refuse to meaningfully engage with the project and provide feedback on crucial things like this.

So are you an admin? If so, we need more comments here: https://github.com/LemmyNet/lemmy/issues/3200

We need to make it VERY clear that Captcha is required before v0.18's release. Not after when we'll all be scrambling...

EDIT: To be clear I'm talking to all instance admins, not just Beehaw's.

UPDATE: Our voices were heard! https://github.com/LemmyNet/lemmy/issues/3200#issuecomment-1600505757

The important part was that this was a decision to re-implement the old (if imperfect) solution in time for the upcoming release. mCaptcha and better techs are indeed the better solution, but at least we won't make ourselves more vulnerable at this critical juncture.

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.
