I'm using Dan Pollock's hosts file method[1] which is detected by Wired and Forbes, but not this site.
At the moment we're relying on a rule in Easy List - https://easylist.adblockplus.org/en/ - it's used by Adblock Plus, uBlock, AdGuard and a probably others. But we need to take into account other methods/blockers that don't rely on this list.
Layer 1: Similar to what @accommodavid has, my router uses several lists of ad-server domains to block requests to them. The list URLs are at https://github.com/pi-hole/pi-hole/blob/963eacfe0537a7abddf3...
Layer 2: My browser has uMatrix. It is set up to only allow a) first-party requests of any kind, and b) third-party requests for images and CSS. (So on your site, the JS from ajax.googleapis.com is blocked.)
