Some people who join new sites do not like answering 20 questions.


Reminds me of the phrase "whats with the 20 questions".


Any way 1 or 2 questions might not be a bad idea.


Like are you human and what year is it.



lol)

20 in the DB
it's put 1 question randomly like "How many fingers usually people have on one hand" :rolleyes:

If we shipped IPB with default questions 99% of people would never change them so bots would already know the answers thereby making them useless. Questions are only good if 1. they are unique to your site and 2. a spammer doesn't take the time to program his bot with the answers :)

But if ipb3 will ask you to add questions at the install/upgrade? :) this way every board will have there own questions.

And in case you see that spammers fit there scripts to your questions, you can always can add new.


I personally 1.5 years ago had a lot of problems because of this Captcha. Spammers killed my board and the only why I could stop them, is by disable new registration. I try it all- different fonts, themes, images… nothing worked until I added those question at the registration.
I can sure you that one or two weeks and your new Captcha mod will be useless.

Very good point.
I am glad it is easy to set up questions using the customer profile fields but it would be nice like the op said if the question was random for one field.

How bout adding a simple question like

2 + 3 = 5 and these questions are generated using a rand command. so they will always be different each time automatically.

If this was a standard IP.Board feature, it would be trivial to update a bot to answer math questions. :)

I think you are unaware of how rand works ....


consider no's 0-9, generate a 9digit no, and see how many millions of combinations can be generated...



Computers were created to solve math questions. I'm not sure it would present much of a barrier to them :) They're quite good at it.

then to be bot proof, do something like google maps



you advertise ur business in gmaps > click submit > and then u get a call immediately



in where u r asked to type in the digits generated on ur screen.

That's getting a little out there for registration on a forum.

The bot could easily be made to read the math problem and solve it. It'd be quite a bit more trivial than deciphering graphical CAPTCHA images.

Something is going on with 2.3.6. I have never seen a "debug_log" in my cache folder. Only error_logs. Well now suddenly in 2 days I have 2 debug_logs totalling almost 300 MB. That's right 300 MB files suddenly in my cache folder.

I looked at another site's cache folder and it has 12 MB of the same type files also. They started on the date 2.3.6 was installed.

I could not get the big files to even open. I opened a smaller one and it has every single query listed.

I see this is already a known issue in the bug tracker and it was fixed yet no announcement of it so I guess people are supposed to just sit around with hundreds of MB of logs sitting there and not be told. lol

For the record, go into ipsclass.php and change the debug log to 0.
