Have been seeing more and more posts "Removed by Reddit" on high-CQS high-karma accounts (with no reports or mention of Reddit filters) for seemingly no reason, often 2 - 48 hours after posting. Haven't been able to detect any similarities between removed posts (subreddit, caption, posting frequency, upvotes/downvotes, whether the Redgifs link has been posted before on other subs or how many times it's been posted). This is all with organic engagement. Does anyone have any idea what's going on and how to avoid these removals?
