Well, I just want to post this because of that :

As written in the .gif image "Just write here stops and bots and replace the o by u", you have to write "stups" and "buts" to post a message ^^

A bot came daily, during one month, made tons of tests, and finaly found the trick, which mean that :
- It found and reconized the .gif file
- It understood the sentence
- It posted its shit ^^

Now that it found the trick, i'll probably get ultra spammed in the fallowing days (like usual).

Some months before, I made another test, this time without protecting my sentence in a .gif image... The thing was "cracked" in less than one week...

----------------------
I have to admit that those bots are pretty well coded, "great stuff"...
It's so impressive that I really wonder if some real humans aren't paid to post shit on boards...

It should be fun to test if they can answer more complex questions like
(60+25)/3+7; or "what color is the horse of henry4"...

I don't think the bot figured it out. I think the bot ran through a suite of common tests which all failed. The owner of the bot then came along, noticed that your captcha doesn't change and modified his bot to handle your site.

Alternatively the bot could just be running a dictionary attack on the captcha fields.

Thx, nice guess :) It's sure that my feedback code is used in million of websites, its a good thing for this guy to code a bot for it ^^ ;)

I'll add a random number generation using the GD, then ^^ :D

How the bot knows that it couldn't post its crap ?

Has something to do with the code control.
