are you sure these are bots???? because there is no way of stopping humans..

Are you serious? How much thought did you put behind this statement? If you feel that this is a 100% fool proof way to stop SPAM you are kidding yourself. Those of you who are still getting SPAM Registers are getting them because they are people and not Bots. I have had this Mod installed for sometime now and have only been SPAM'd 3 times as opposed to all the time before the Mod. Therefore, and I am not alone, this Mod is well worth the price.... which is free by the way.

yeah very true it is but I know they were spam bots who had got past mine I installed https://vborg.vbsupport.ru/showthread.php?t=147280 and poof there went the spam bots not one since i have installed it which is over a week now when even with this mod installed I was getting them everyday.

i forgot to come here and tell you all how happy i am with this hack. this hack is the best hack ever. it keeps my forums just about maintenance free...

i used get AT LEAST 2 bots joining per day..and thats AT LEAST no less.

It has been 2 weeks since i have installed this hack, and not a bot or spammer has joined.
i must say i am very very impressed with it!!

hahahaha for some reason i found that sentence very amusing.. the bot & human thing..i must be tired lol!

perhaps u need to always update ur images...if they study ur images they'll know each of them...and having a lot helps also i believe

We have a question in our registration process that asks for a Biography... bots are always answering "Man" to this question. Humans either skip it or enter random stuff.

When I first installed this hack the bots were done instantly.. 4 days passed without a one. Now they are back again.

My guess is that they have figured out a way around this. That or they are flat out guessing the answer to my quesitons, which I doubt. Or, these are humans who are using automated software to help the registration process (like autofill) so they are able to actually see the question and answer.

At any rate, it went from about 6 a day to 0 in 4 days (post install) to about 6 just today again. Bummer.

Phew, I haven't been on for a while.

Whoever asked for a feature to allow people to put images as the question: all you need to do is insert the HTML for an image as the question, as HTML will be parsed.

Everybody who has it installed and working but is still getting spam, I'm afraid this hack is logically 100% bot-proof until the day they create bots with flawless human intelligence, so if spammers are getting through, they are clearly human and impossible to stop with any sort of anti-spam system. (You could, of course, try to make more difficult questions - if, for example, all your questions are simple math problems, it is quite possible for bots to be programmed to pick up the numbers and mathematical operations from the string of text and enter the answer in a field, while if you ask random common-sense questions (and especially, if you own a specialized forum, answers that require some knowledge in a particular field that true members would have), they will be impossible for a bot to crack, and if they're difficult enough they might stop human spammers in their tracks as well, as they will not bother with spending time trying to Google the answer to the questions or something just to register at one forum.

The reason it is bot-proof (at least with decent questions) is that the answers to the questions are stored only on the server. From what I could understand of that other hack that will present the user with a choice of images, it offers very weak protection since the answer is in the filename of the image and all a bot programmer would need to do is be aware of this fact and make the bot extract the answer from the page when it is presented with the question. Here, there is no way to just retrieve the answer; it is all stored in the database, which the bot can't access, and the answer is never within the reach of anybody who does not actually know the answer to the question. Since bots do not have the artificial intelligence to be able to read a question, understand it and have the knowledge to answer it in more than some extremely limited cases (like the math questions mentioned above), it is impossible for them to get around it.

Does this hack work on 3.6.7 PL1?

works fine on mine
