Legitimate sites in blacklist

[chiara-paci]

Hi.

I'm trying to implement blackweb in the proxy of one of my clients, but there is something I can't understand.

I activate it in a test environment, and it's blocking almost everything, including:

• well known sites like apache.org, docker.com, pypi.org, etc.;
• banks like unicredit.it;
• almost every italian provider (tiscali.it, virgilio.it, libero.it, etc.);
• governative institutions (sogei.it, rai.it, provincia.tn.it, etc.).

Why are they included? How can Sogei, owned by a ministry, be in a blacklist?
