Just a thought and something I saw in another forum which might work very well.

Why not put a special set of questions in the registration, questions which only a human can answer.

Such as "Are you human?" and many other questions that dont make sense to ask but can be answered correctly by anyone who is human.

Maybe 5 of these would do really well.

Sounds reasonable enough, and heck, it might just work.

maybe for "are you human" there could be image boxes for the answers.

Maybe two radio buttons that says yes or no, then a input box with an image instruction that says type a sentence Yes, I am human. I doubt that a bot can do that. In anycase if a bot does get it the only means that someone is messing with us.

I saw the human checker option and other methods. The problem is more when I will have the free time to mess with the script. Hopefully soon because the bot problem is out of control.

Well, we have it under control, usualy no bot post lasts over 24hrs. Its just that they keep coming every now and then.
