It may or may not be. I can't speak to that post, but I've seen others pull the same bit with other posts (wait a week or two and repost with a gender swap, then point to the radical difference in response) and usually the gender swapped version gets deleted and the poster banned when it comes out.
Yeah always had a good chuckle at the people that would try to point out the echo chamber hypocrisy in a subreddit and be upvoted but yelled at so hard then banned.
