I remain unconvinced that capcha inhibits bots at all, there are so many capcha cracks and solving services out there now that I truly believe capcha has had its day, all it's doing now is making life a bit harder for blind people. You can get google capchas solved as cheap as $0.001 each!

It greatly reduce the bots, sure it depends on the complexity of the captcha.

Some captcha are easier to crack than the others. The ones commonly used with plaint text on uniformed background are easiest to solve. I am surprised that there aren't many captcha generator that overlays text on a image with post processing features.

Yeah it sucks for the blind. But this post is about submitters, which is unlikely applicable to the blind users.

That's another way and the least effort way of doing it :-).

A forum where my work colleagues installed google's capcha around xmas 2016 saw improvement lasting about 10 days, then no measurable decrease in spam type activities over the next 12 months, the figures simply don't match the claims.

Programatically yes, I agree, but they're all easy when they're being done by humans in a boilerroom operation.

I know for sure there's at least one blind user on here, born that way, lives about 2 miles from me. He won't let me name him but he's been submitting for at least 3 or 4 years now, used to call me sometimes for help getting past google's capcha for here and elsewhere, hasn't done so for a while now so maybe he got someone closer to help him. I used to know another, think he only submitted a few articles just after the fappening exodus, died last year. So that's 2 blind users in a pissant little city in the middle of the UK, what's the chances of there being many more? On the internet nobody knows you're a dog (or a blind person).

I get journals from a website that uses a sort of in house bot deterrent. It asks that you select the image of Albert Einstein in a lineup of random images, one image containing Einstein.

Maybe voat could implement something similar.

That would be a good idea if Voat already has such database of images that are already tagged with names of people or objects. If that is not the case, it may be too much work to build a reasonably sizable collection of images. Generating alphanumeric values, on the other hand, can be done using scripts or other tools, eliminating the need to identify the anticipated responses.

But I think we can combine your approach with this alphanumeric captcha. For example, it is easy to super impose a generated alphanumeric value onto an arbitrary cut-out image and apply some readily accessible image processing operations. I would imagine the resulting image will still remain identifiable to a genuine user; yet, it would be difficult enough for the bots to solve. Why? Because the bots not only have to solve the alphanumeric values, but also need to perform things like edge analysis or segmentation, which aren't trivial if one doesn't have computing horsepower. This method of generating the captcha can be precomputed and done offline with minimal effort.

Eh, you only need 6 images, one of which is Einstein. Throw together some random number generator to list the pictures randomly from 1 to 6 with the Einstein as a key image. If the number recorded for the Einstein image matches the remembered number then chances are it was selected by a good observer of images.
