I've seen banned accounts on my drupal site use the same email address and register again, just by adding in a period to their Gmail account. Making the trolls jump though one more hoop (can't use same Gmail account) would be a plus IMHO.

Or for me to be able to identify them after the fact. This would be a nice feature.

So, like, a "similar" email list?

Please give some concrete examples of the email addresses you would like to see listed as duplicates vs nonduplicates.

How could this really work... what about a config option where the admin could specify characters to ignore? Like: spaces, periods, etc. It reminds me of in captcha how you can specify which characters to *use*, would be opposite. And I remember seeing an issue or doc or module somewhere where the roman character encoding *looks* like the regular character, but is different. I dont know if that is just usernames or a concern for emails.

Lets clearly stick to the mail field, for now, though.

admin@gmail.com
a.d.m.i.n@gmail.com
ad.min@gmail.com
Ad.min@gmail.com
Admin@gmail.com

These all point to the same inbox on gmail, being able to detect this would be nice

Ah, I see... http://mail.google.com/support/bin/answer.py?hl=en&ctx=mail&answer=10313#

First thought... this is hard.
What are the options for using a regular expression, or code? How would this work with the query?
