The fake emails that the Twitter Blog mentioned the other day, Reports of Fake Twitter Emails, continue to be sent out. Some have said that you have delayed messages at Twitter but of course obscure the URL in a HTML email and then send you to different sites. Some of these sites may send you to malware infected sites or just be trying to drive traffic to their pages.
I just received a variation of the email that looked like this:
This one is saying I have an information message and appears to come from Twitter Support with a faked From address on the email. The URL is to another site completely however, the small Twitter Support link at the bottom of the email takes you to the genuine Twitter Help Center and is probably an attempt to show you that it is a legitimate email.
My recommendation is that you simply do not click on the link and delete the message.
