Block an email address

Bump. I would like to know, as it was available in 6.x

I am pretty new at this, but this might be helpful.

Since I had more spammers signing up on my web site than real people, I found the http://www.stopforumspam.com site which helped me to determine that these addresses were from spammers (though the strange names helped). In the configuration>>people>>IP blocking section, I started blocking the IP addresses (which helped some). But one spammer used a number of IP addresses with the same email address.

I had installed the Mollom module as recommended by the Drupal 7 Manual book by David Ipswich. This module is controlled under configuration>>content authoring>>Mollom content moderation, which has a blacklist tab. On that tab, I am now selecting the 'Author e-mail' and blocking that email setting. I think that will work, too.

Experienced users may have better comments.

Yeah Mollom is a good choice. You might also try Honeypot.

Webform has never provided this feature as far as I know.

You could also try installing Webform Validation module to set up explicit "Field must not contain some string" validators.
