Purebloggers.com ?

I got a random very plain email this morning from purebloggers.com telling me someone recommended my blog to their site & if I wanted more readers I should join.

I know better then to click any links in a random email so I did a search instead.

Seems to be that they're sending that email to any and everyone that has a blog.  

I'm not going to join, but I will keep a tiny eye out for them in the future. I honestly feel it's just a phishing site.
