I have been threatend on my new blog

I haven’t even finished setting up my wordpress blog yet today I received some threatening comments on my site. Here they are with the vulgarity left out….

(1) “I received aan email telling me to re-register my craigslist account and it originated frome a site that is connected to this webpage. WHY. That email is an ILLEGAL attempt to obtain my personal information. It has been reported”

(2) “You are so #@%*$#@!”

(3) “When I catch up with you I plan to kick your teeth in.”

(4) “stop trying to steal my *&&^ or i will destroy you.”

Anybody want to tell me what is going on? I have never visited “Craig’s List” and would not know how to impersonate anyone even if I did!!
