Either Python or PowerShell would work for the scripting.

If uBlock Origin uses filters, would it not be possible to build a program that acts as a "proxy" for Linux/macOS/Windows, etc., that uses the same or similarly crafted filters to do something akin to what some of us did back in the Flash LSO supercookie days? I was a Linux user then and I recall creating a symlink from .macromedia and .adobe to /dev/null. The cookies were written to their folders but went into the event horizon of /dev/null and I never had to worry about them, but the websites worked like a charm.

Maybe I'm wrong, but would it not be possible to use filters similar, or even different than uBlocks, to "symlink" the addresses to /dev/null or other bit bucket like NULL on other OSes? I write automation code, so I don't have the chops to develop such a program/project, but I can see it in my head "how it might work". Thoughts, ideas, criticisms welcome.

I've also taken to using Violent Monkey and scripts to block quite a bit of nonsense on the web. Violent Monkey and the iFrame blockers work well with YouTube. I suppose it's also a matter of time before things like Violent Monkey are removed as well. There has to be a way to proxy the traffic through a filter list and /dev/null the offending objects.
