hello,
recently I saw these weird people talking things that don't make any sense.
so I thought I would give you guys a tip on what I used on my previous forum to prevent having to deal with bots.
I used a php plugin based on object recognition in an image
for example you get some small sized pictures of cars & some of cats
then when someone registers he sees a selection of those pictures & need to check the correct boxes (for example the instructions would be : check pictures of cats only)
it worked very fine on my old forum, I was rid of 100% of any bot registration
(even though the day they work out the thing, they may be able to get through but they have a very small chance of passing through, depending on the number of images shown to the user)
advantages:
-it's not as widely used as the standard CAPTCHA with text written which means an extra layer of protection
-some photo-text based CAPTCHA are hard to read depending on the quality of your human eyes, this mod does not pose that problem
inconvenient:
-people are not used to it, so you may occasionally have to deal with the guy who email you because he's a dumb ass who don't want to read instructions (which are neither long nor hard ...)
For security purpose I won't give any links in public, so if the person in charge wants it...
this mod exist for both phpbb2 & phpbb3 (have not tried phpbb3 version though)
PS: I know that the forum still needs to be upgraded, but I posted this now that I think about it ;)
edit: ho and one last tip even though it's obvious, some people forget it and then we are doomed, always make a database + FTP backup before any modification
