Stopping excessive spam bot registrations?

[crl]

I am getting a lot of spam bot registrations lately on two of my photo galleries both running the latest 1.5.44 versions. For new registrations I am using the standard " Display Captcha (Visual Confirmation) on registration page" option. So my question is there a better Display Captcha system that I could use? or anything else to stop these spam registrations?

In addition, you could research creating rules on the server side to prevent certain countries from registering. Most of these registrations come from just a few countries which you can usually work out from the IP address. If you do a bit of research you can block these using various methods, from .htaccess additions, to server side rules. You would probably be best talking you your host about how to do this as they can be very specific to your hosting.

Currently on one of my installs, I was getting hundreds of bot registrations per day from Nigeria. I block that country and they stopped. Also worth noting however that sometimes these kinds of registrations can be down to your server already being compromised. If a nasty hacker has left some iffy code then that also needs dealing with.

Thanks I will certainly look into your suggestions.

Is there a mod around to create a specific registration question and if answered incorrectly the registration will fail?
