Sometimes these "security" solutions make you wonder whether someone took the joke about a machine without a network connection being the most secure seriously. First visit ever to this domain and:

   Sorry, you have been blocked
   You are unable to access jazzwise.com

   Why have I been blocked?

   This website is using a security service to protect itself from online 
   attacks. The action you just performed triggered the security solution. There 
   are several actions that could trigger this block including submitting a
   certain word or phrase, a SQL command or malformed data.

Some blacklists last forever even though most ip leases only last a day or two.

Same here!
