Captcha

You know, I should really just play my 'expert' card at this point :P

I have written my own CAPTCHA. As far as I know at this time it has not been broken by bots. It is specifically designed to resist conventional OCR techniques without being overly unreadable.

I have also written multi-language Q&A.

Due to the situation in which both were written, neither can be just dropped into SMF but could be adapted fairly quickly.

Neither is a particularly hard task if you're competent and know SMF - the former took a couple of weeks of research and development, the latter took... no more than two days and probably less than one in the end.

ask the translators to help out...

There aren't active translators for all languages though.

As for covering all the languages, if you already have language moderators and translators, it seems to me it would not be a large task to ask them for the questions.

If there were more active translators, then this would be an option, but that's not the case at the moment.

If there aren't active translators for all languages, presumably the userbase from those languages is small enough that it wouldn't actually matter not to have those languages supported.

Curiosity duly peaked... :P

Oh, come on! With the words that I'm suggesting, even Bing translate would be good enough, Shirley?

Illori

if it is easy enough you can use a bot to translate it, it is too easy to use.

Not necessarily, no, although in some cases that would be correct.

Are we talking about the same thing, 'chele? I'm still on the pix and asking what the image is a pic of...

Arantor

K@ - check out Wedge's registration. Or the registration on Bryan's site, I left him a copy of it way back.

Ultimately if there is any text in a CAPTCHA challenge, it will be an issue for language speakers because the text has to be translated. Putting it in images doesn't necessarily help anything.

Irisado: True enough. But I'm operating on the principle that while it's a compromise, to me it's a better compromise than the current situation and if it were actually a problem, I'm sure some of the people from those languages would be able to help perform translations...

the image description is still going to be very basic... basic means easy for bots to crack

you give choices and someone will find the answer even if just by guessing

Bryan's is screwed, Pete.

The "D" could've been an "O". I request another image and keep getting the same one. :(

Certainly better than the standard one, though.

Bots can discern images, can they? Coo.

Arantor

Firstly, O should never come up in SMF CAPTCHAs (mine included). It specifically excludes some letters where there is ambiguity in the letter forms.

Secondly, getting the same image is a symptom of browser caching, not the CAPTCHA itself; the odds of you getting the same image are very very tiny - it doesn't just generate one type of CAPTCHA, it generates several visually distinct styles.

Thirdly, in the much better version I have, it doesn't use SMF's fonts at all, so the ambiguity aspect is less of a problem ;)

And yes, bots are getting to the stage where they can discern images. Reading text out of images is years old as a practice, discerning images when you have a set of exemplars to work with is no problem.

I did look more like a "D", to be honest.

I MUCH prefer that to "normal" CRAPTCHAs, I have to agree.

Kindred

Arantor...

I think we all agree that support for multi-language questions (and potentially multi-answer questions) are probably the best option.

Obviously, it's not done for 2.1 -- but inclusion for 2.2 or 3.0 (whichever is next on the schedule) is something that should be considered.
I recall having this conversation between you, me and MrPhil already and I though we had actually come up with an outline that would not be difficult to implement.

That's the point... both Wedge and Elkarte already have it!

The other Phil

I concur that the captcha's are terrible. I don't think I'll make it to ten. This is probably my last post. If your goal was to keep away new participants, you've succeeded.

Arantor

The goal is not to keep new participants away but to try (in vain) to keep the spammers at bay.
