Reddit RSS feeds hit by HTTP 429 rate limiting errors

Jeff Johnson describes his long-time use of Reddit RSS feeds to follow Apple-related subreddits, customer support subreddits, and local Wisconsin subreddits. He reports that starting yesterday afternoon, all his ~25 Reddit RSS feeds began returning HTTP 429 Too Many Requests errors, indicating Reddit has implemented rate limiting on RSS feed access. He found confirmation of this issue in Reddit posts from other users experiencing the same problem.
