Best guide I found

https://old.reddit.com/r/privacy/comments/euud7u/how_to_prev...

I updated their blocks to cover all the IPs in the range, windows firewall rules accept CIDR notation ala 72.25.64.0/18.

All the ranges for their backend stuff I've found so far:

  72.25.64.0/18
  216.228.112.0/20
  8.36.80.0/24
  8.36.113.0/24

I leave mapping out the rest of their IP space as an exercise to the reader.

Found using `whois` against the IPs and domain from that reddit post. Their primary website appears to be on EC2, so nothing terribly useful there. I'm personally expecting companies that do this nonsense to move all their collection infra to EC2 or similar to make it harder to do simple blocks. Those that haven't already.
