22.7.4/Proxy ACL Blacklists (external)

[PotatoCarl]

Hi
I found that it seems a number of external ACL blacklists do not work anymore. So I searched for new ones and I wonder if I can test if they are good and active. Some pages (e.g. www.spiegel.de or www.faz.net) manage to dump a lot of advertisement on the page - that is funny enough not displayed on a reload of the page.

So I wonder if the ACL is working correctly.

Any way to test this?
