I have already talked about this thing to CyberShadow
Control system Wormnet has banned all users with Italian ISP as "FastWeb (http://www.fastweb.it)" (We are many)
This type of Internet is like a big LAN ... For this reason many users often use the same public ip.
Please remove this ban... we can't join wormnet!
Our network is clean.
Thank you

I've already told you, we don't control the blacklists. You received a link to the blacklist website, why didn't you just follow the removal instructions there? Check your IP's presence in DroneBL (http://dronebl.org/) and the EFnet RBL (http://efnetrbl.org/), and remove yourself from either blacklist.

I can't do that!
I m not the owner of my ip!
Only my Isp can

FastWeb Suck!!!!!!

Edit: RBL approved my removal request

Just wait for your temporary ban to expire, then.
