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.

Why would devs remove something like this, at this time? Is it causing huge problems larger than the problems removing it would cause?

Makes me wonder if the devs are being paid to cripple Lemmy. This is where open source shines, we don't have to be held hostage to one product/service.

Devs be enjoying vodka. Their vision is too blurry so they wanna get rid of the captcha so they can make secret accounts on other instances to shitpost.

Just created the instance, now the spammers consumed all my email allowances today :( I just enabled CAPTCHA now, now I'm gonna wait till tomorrow how much this makes difference.

There's nothing stopping instance owners from incorporating their own security measures into their infrastructure as they see fit, such as a reverse proxy with a modern web application firewall, solutions such as Cloudflare and the free captcha capabilities they offer, or a combination of those and/or various other protective measures. If you're hosting your own Lemmy instance and exposing it to the public, and you don't understand what would be involved in the above examples or have no idea where to start, then you probably shouldn't be hosting a public Lemmy instance in the first place.

It's generally not a good idea to rely primarily on security to be baked into application code and call it a day. I'm not up to date on this news and all of the nuances yet, I'll look into it after I've posted this, but what I said above holds true regardless.

The responsibility of security of any publicly hosted web application or service rests squarely on the owner of the instance. It's up to you to secure your infrastructure, and there are very good and accepted best practice ways of doing that outside of application code. Something like losing baked in captcha in a web application should come as no big deal to those who have the appropriate level of knowledge to responsibly host their instance.

From what this seems to be about, it seems like a non-issue, unless you're someone who is relying on baked in security to cover for your lack of expertise in properly securing your instance and mitigating exploitation by bots yourself.

I'm not trying to demean anyone or sound holier than thou, but honestly, please don't rely on the devs for all of your security needs. There are ways to keep your instance secure that doesn't require their involvement, and that are best practice anyways. Please seek to educate yourself if this applies to you, and shore up the security of your own instances by way of the surrounding infrastructure.

I think that's a heck of a loaded assumption there that I'm relying on the Devs here

Cloudflare ✅ Strict Firewall Rules ✅ Hosting on an actual cloud provider rather than my home ✅ CSAM Scanner ✅

However, that's come with other tradeoffs in useability, speed, and fediration experience.

Just today I found that the OWASP managed rules in Cloudflare end up blocking certain functions of the site, sure I'll be adding an exception/rule for that, but it's not a straight forward task. Heck, the removal of websockets will require quite a few changes in my Cloudflare config.

Sure, someone truly concerned with security knows to do this, but that's definitely not going to be everyone, and now with the current spam situation we're turning individual instance problems into "everyone problems".

While I am glad that they listened to the community. Everyone seemed to forget that you do not have to upgrade to the latest version. If the risks outweigh the benefits it's perfectly fine to stay at the last working version. There is also the possibility of backports and manual restoration of Captchas to get the features you want out of the later versions, if you have the development skillset to do so.

I don't have a responsibility to do anything. This isn't my issue and you can't force me to care.
