Wouldn't provide useful info
You see an ad and below it is says "sponsored by Campaign Against Wearing Masks" or "sponsored by SWCA" what does that tell you? The really problematic stuff isn't sponsored by the parties or campaigns, it is sponsored by organizations you've never heard of. If they are worried you might have heard of them the dark money groups can set up a shell company they create just to run ads on Facebook for a couple months".
Good luck getting information about who owns them, especially if they are deliberately doing shady things and are operating through enough layers that there's no way to tell where their money came from.
