I found this by searching "modal" on filterlists.com and clicking the subscribe button. IMO there should be a Medium-specific one like they have for stackoverflow or youtube.
I cannot personally vouch if the modal filters are overzealous. I'd rather avoid Medium than putting up with this sort of thing.
I only found the "one-click" subscribe for the masterlist in the repo readme. Additionally I couldn't link a specific filterlists.com result to the modal filter "one-click" subscribe that I use.
I'd have preferred a ublock subscribe link but I'm not sure how to make it clickable without an href.
