You should study the OSI Model. MAC addresses are layer-2 addresses in a frame, but frames are stripped off at a router. IP addresses are layer-3 addresses in the packet. Only packets will cross a router.
Hosts and switches use MAC addresses in the frames to deliver frames to the correct host (including a gateway, which is just another host on layer-2) on a LAN. When a gateway (router) gets the frame from a host, it strips off the frame header to get to the packet, and it routes the packet based on the IP address. When the router sends the packet out the new interface, it will create a new frame encapsulation for the new link, using its own MAC address for the new frame. As a packet moves from router-to-router to its final destination, the only surviving source MAC address will be that of the final router.
unless you're using IPv6 with a EUI-64 address. In that case, your MAC address could be derived from the IPv6 address. But the chance of that is slim as hell.
Reddit doesn't have any scripting to scrape your devices MAC from your browser either.
You seem like you know your shit. This is somewhat related...but Ive been doing some research regarding social media shadow banning/throttling/controls (specifically facebook). I think ive stumbled across something big but i am needing some direction and technical guidance with it. Can i shoot you a PM and get your thoughts/insight on this?
