New Follower email includes link to spammer's web site

Spammers are using the 'Full Name' to place a direct link to their web site in the New Follower email. Normally, the only links that are available in the New Follower email are the link to the user's Twitter profile page and the link to the Notifications settings page.

For example, porn spammer myzine.com (nsfw) is using this technique by setting their Full Name to "myzine.com". Most web-based email clients - e.g. Gmail - interpret any text with a .com attached to it as a URL. Normally the Full Name is just plain text - John Smith. A screenshot of this is available here: http://urltea.com/341u . Notice the hyperlinks on myzine.com.

I'm proposing that you change the Account Settings page to disallow web site extensions in the Full Name - .com, .org, .net, etc. Or just disallow the period altogether.
