Been working on this a bit – I havent fully tested it - so I wanted to get it out there and see if others could find value in it.
Its a personal proxy and cookie jar for starting to collect and figure out and then block brokers. I have another project which is more ambitious - where I have been looking up and building a table of every IP address, ASN (Autonomous System Number - the ASN is the “address” used in BGP Border Gateway Protocol routing - which is basically how the internet routes (though there is a lot more new stuff) – but the goal is to collect every IP space belonging to the PFAANG groups and their subsidiaries, and the data brokers and build a massive IP blacklist.
