Should I Renew A Randomly-Named Domain?

I need your help. I received the following via electronic mail this week:

This is your last chance to renew your domain name(s)! YOU MUST RENEW BY Mar. 29, 2008 OR THE DOMAINS LISTED BELOW WILL BE CANCELLED.


Should I renew it? Please comment with a firm “yes” or “no” and any reasons why you feel so.
