Edit: I've been rate limited because of this comment, apparently. Account burned - will make a new one. Dang says below it's because of flagged comments but I don't see many flagged comments in my history.
We rate limited you because of flamewar comments you posted in another thread, like this one: https://news.ycombinator.com/item?id=48723651. You posted over 50 times in that thread, and many of your comments there broke the site guidelines. That's abusive. If we didn't rate limit accounts for doing that, we might as well have no guidelines or restrictions at all.
