Someone correct me if I'm wrong, but I'm fairly certain /r/The_Donald already didn't have ads on it as the article implied it did. Reddit only allows ads in white-listed subs and T_D was never white listed AFAIK.

Edit: Found where I read this: https://www.reddit.com/r/stopadvertising/comments/85vdwo/gro...

Edit 2: my comment was moved from a different thread that was on a TechCrunch article on this. TechCrunch claimed that this quarantine would mean that ads would no longer run on T_D.
