Too many spam members joining up. How to stop this

I have a version of Dolphin 7.1 setup on a domain.

The number of spam members signing up is driving me nuts.

Is there a way that I can close off membership and make it by invitation only?

There are many threads on this and several modules in the market. Just do a search and pick a solution that works best for you.

Anthony, In the top right corner use the magnifying glass icon and search for "Human question". Check out Deanos tool for spam if you like and make sure you are using Captcha and confirm email.

I have a spam filtering mod that stops most all spam.

There are also solutions in the forums.

The best way to stop spambots from signing up is by using recaptcha and email confirmations. It is not perfect but it is a first step.

I also released my Bot Stopper module yesterday which is very effective in banning spambots that already signed up. I wrote it for a customer who's site was infected with bots causing the site to go down, sometimes several times an hour.

The easiest and 100% working protection for me  was simple security question.

I have been using this protection for more than a year now, and no spam at all.

And it is free.
