Thank you very much for this mod! It works like a charm and has kept out automated spammers, yet.

Btw, I translated the few english text lines into german (all but the questions since I only used one new question).

Hi Derek, I assume this anti-spam mod won't work oni 2.3?

Hi again Graham,

It should work fine, it's just a search string or two which are different. Try the .mod file attached to this post (again, I've not tested) - you'll obviously still need the other files from the package attached to the first post.

You might also want to check out Carsten's 'SpamFruits' Mod if you're interested in this. From having a quick look, it looks like that will work with 2.3 how it is:

http://www.carsten-dalgaard.dk/cgi-bin/yabb2/YaBB.pl?num=1318072608

They both do a similar sort of thing really, so you've got the choice which one you want to use.

Edited:
Nov 9th, 2011 at 10:22pm - Edited to update the attached mod file to the latest version (0.2).

Yes, you could do, but I don't know how much point there would be in doing so. That would probably be a little 'over cautious'. Also, neither Mod will stop human spammers - they will only stop bots, and both Mods should work okay by themselves at stopping bots...

Derek,

Thank you for this.  I have a 2.3.1 board and have been buried this week by registrations from bots that can solve captchas in just a few seconds.  The result is quote a mess of crap waiting for an admin to sort through and delete all the bogus registrations.

I just installed your mod v0_1_23.  Nice.  This should stop them cold.   Cool

Thanks Autonerdz. You'll have to let us know how it gets on - it would be nice to know how well it works.

I think I had the first person/bot get past it yesterday on my test board, but I suspect they were human - Along with the other checks though, they still didn't manage to get through.

Derek,

It stopped them right in their tracks. 

I was monitoring the error logs while trying other things like making the captcha more complex.  The bots still solved it faster than a human in just a few seconds after four to six attempts generating the validation error.

After installing this mod, they still generate the validation errors.  I think some of the bots may be placing the validation response in the challenge question field.   Grin

Others continue until there is a verification question error.

In any case, not a single one has made it through to the admin approval stage.  Sure made my life easier. 

Thanks again.... Smiley

Just carried out the mod; very straightforward - thank you! Smiley

Will have to wait a couple of days to see the effect this second level of verification has (I too have left the captcha field in the registration process, even though the bots seem to have got the hang of it!!).
