More simple than that - I'll likely use AutoItScript for windows - literally automate clicking links or simulating keystrokes (like the tab key) until it reaches the desired link then clicking the edit function, revising text, tab to the save button, saving change, and repeat over and over.
It's crude and inefficient, but I have over twenty years experience using the code for various small tasks so I'm sure I'll get the job done.
Just not sure when I want to start - I feel like they are still playing tricks un-deleting content and such for people using automated API code. So for now I've simply blocked reddit at the router level for another month or two before I go back and start writing my code to automate the deletion of 10+ years worth of content.
