fake newsletter signups

I have a lot of email sign ups that I suspect are fake. A lot from nextflash and mail.ru. Is there any way to prevent these so they don’t overflow my database? Thanks

Have you got image verification turned on?



John

I don’t see an option to turn it on for newsletter signups. Would be nice though!

Sorry thought it was std

Do you ship internationally? I block all ripe and lacnic ip addresses via htaccess.



EDIT: Ripe = Europe, the Middle East and parts of Central Asia

Lacnic = Latin American and Caribbean
