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
Sure, so implement them in v.0.18 rather than leaving that essential feature for a future release - that's all I personally want.
I don't care about the technical implementation of the Captcha, but given the current threat landscape of low effort bot attacks, removing the feature in the meantime just makes the fediverse worse off.
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.
To be fair, "Captcha" can now mean those ai photo discrimination tests. Captcha: "Select the cats" - Me: "You call these cats?" Looks at the cartoon depictions of nightmare fuel "cats" as depicted by Picasso.
There are still graphical tests we perform that are much harder for computers to perform - at least without near-nation-state sized financial backing.
Yes, the ol' scrambled captcha has been solved by multiple approaches these days, but Its not nation states I'm seeking to keep out (and I'll be fucked if they ever did, I might add), I'm just looking to make it harder for some internet edgelord's low effort spam attempts.
Sure but you can pay a company in India a few bucks for a few hundred captcha solves. It doesn't matter what the captcha is, because a human is actually solving them, you're just outsourcing it for literal pennies. It's not difficult, either
Look, you keep returning back to a point I'm not making, and it seems like its in bad faith.
You keep saying how captcha's aren't perfect. They never needed to be and any sufficiently advanced attacker can bypass them. We've gone over that at length, you returning to this argument just shows how little else you have than "Mondays always suck" / "Evil shall persist" mindset.
Your entire position of chasing me on "oh, but captcha doesn't solve ALLLLLL bots". Yeah, and laws don't deter ALLL crime either.
Shall we remove these pesky laws of civil society? I mean, after all why abide by rules that any one person can chose not to follow the laws? What good are they anyways?
You know it's an inane point that has no logical conclusion, but I think you probably already know that and I'm done assuming good faith in your trolling.
Seems to me like you're mis-framing what's being said to fit your argument and claim the other person as a troll. No one has made a claim about stopping "ALLLLLL" bots or "perfection". It's about whether it stops enough to matter. And I think it's safe to assume if someone had the interest and capability to write a bot, they can probably google "how to defeat captcha" and implement one of them. If there's currently not a flood of bot accounts, I believe it's from a lack of caring rather than the captchas doing anything.
There are solutions for bots, they should be implemented, but keeping the existing captcha isn't worth it. Multiple things can be true, but I get the feeling you're set enough in your opinion that you're going to (continue to) attack the character of anyone who disagrees.
Not entirely sure about the misframing thing, because I see a pretty clear pattern of arguing towards perfection, I'm not sure how one could look at that and not arrive at the interpretation. It didn't seem to matter how complex the task was, the point was always "that version can be overcome - it's pointless".
All the while missing the point. If we're arguing "stops enough to matter" then the answer is self evident. The captcha is currently the difference between a bot problem and not for many and that's what's happening now, not in the future (as near or as distant it may be). Multiple things can be true indeed "This is a bad implementation and needs replacement" "this is currently stopping things from getting worse", but that doesn't also mean "We should remove it now and not worry about a replacement until afterwards".
I'm not saying they're not perfect, I'm saying they're effectively worthless. They're so easily bypassed that it's not worth supporting in the first place.
Then it's no longer only a bot, right? There are real humans working on those captcha farm. Those captcha farm also won't solve the captcha instantly, but there will be some delays for a human to solve the captcha. You're effectively turning graphical captcha into proof-of-work captcha this way, which will have the same effect as mCaptcha due to increased cost (in this case, captcha farm cost instead of computational cost) for the bot operator.
Because this spam-bot seems to be currently only targeting these instances.
So what you're saying is that a poorly constructed door is better than none at all? Huh. That was my exact point.
No I am saying the this bot seems to specifically look for instances without captcha and doesn't even try others. Low hanging fruits and all that. If all admins enable captchas the bot would just switch to those and circumvent the cheap captcha that is currently implemented in Lemmy.
So the solution is to force everyone to be low hanging fruit in the meantime?
Look, I get where everyone is going in terms of improvements, but to remove an already working solution and leaving folks exposed in the meantime is not how we should be rolling improvements.
See my other comment. Lemmy already implements other ways to prevent this from happening that are much more effective.
Email validation works only until my domain get's blacklisted...
Manual registration only works up until a certain size...
What other effective solution shall I consider? Those aren't very effective to me.
If you reach a size where manual approval doesn't work anymore you should seriously consider closing registration completely or increase the size of your admin team.
