|Question: Textual Confirmation has been working well, up until recently. I am now getting a large amount of registrations and spam messages posted.
Answer: Try to change the questions because some classes of them seem been compromised:
* With yes/no/true/false answers
* Probably arithmetics (1+2, etc)
* Probably with colors name answers
Also, I released Advanced Textual Confirmation. This tool implements more checks and can protect from the recent generation of spam bots.
