Reddit presents themselves as a "platform for communities", not as a singular "community" (I'm paraphrasing kn0thing, I believe). This is directly in opposition to that ideal: previously, the administrators have only really interfered with, well, a bunch of subreddits targeted at pedophiles. Now, they're imposing blanket domain bans across every single Reddit community. I don't think that anyone would have a problem with allowing subreddit moderators to ban domains. I'd love to see image and meme hosts banned from almost everything to enforce high quality articles.
The Atlantic is a common sight on TrueReddit. I don't care if it was posted by an employee, because TrueReddit subscribers are pretty good about downvoting anything that doesn't fit. What I do care about is being able to read the great articles from The Atlantic that are upvoted on TrueReddit. However, the Reddit administrators have decided that I, and every other TrueReddit subscriber, shouldn't be allowed to anymore.
This is a fine technological decision, instead of spending years on heuristics, but it's implemented at the wrong level.
