An up-to-date list of advertising and malicious sites for SQUID - where can I get it?

Question

Squid

The organization has a Squid proxy server installed (are there any alternatives?)
Ad blocking by domains is set up - less than 20 main ones (google-analytics.com, googlesyndication.com, etc.)
as well as several dozen URLs.
Is there any solution to keep the ad/malware list up to date ?
Existing options (eg adaway.org/hosts.txt , someonewhocares.org/hosts/hosts , etc.) cover the entire Internet, but at the same time do not contain most of the Russian banner networks.
I see options:

• Using Safe browsing API Yandex, Google
  
• Using lists of leading antiviruses - but it is unlikely that they will freely provide such data? But you can try to pass SQUID traffic through a machine with a licensed antivirus (and a link checker) installed...
  

The question also arises - how big can the SQUID block list be without significant performance loss?
acl bad_sites dstdomain "/etc/squid3/bad_sites.txt"
In what internal format does the list proxy work - does it index or not?

Answer 1

At one time I asked myself the same question. Here is what they answered me:
"there is such a project - Rejik - carefully read what it is and how it works, then register and request ban lists for verification; a page with 10 links is sent to your mail and you must determine whether they belong to the declared category or not.correct answer +1, incorrect - minus the entire list, i.e. -10.upon
reaching 200 points, your "money" account will begin to increase, local money is called BANs.For 10 BANs, you can download the full list of BANs once
There, on the site, in fact, everything that I said is already written. Check it out.
If you want everything to be simple and fast - an annual subscription of 2 kilorubles .
By the way, I have already been reproached once for allegedly advertising this far from free project here.
It's not like that, I've been sitting all weekend and checking these fucking links! You have no idea how boring it is "
