RickReddit has removed any mention of the protest from the front page
Suspicious but it could just be posts aging out.
That's not how reddit normally works, they are aging out VERY fast for the amount of upvotes they have
I just went and looked and the posts from about 13 hours ago are down to page 3 of hot, while the posts from almost 24 hours ago are just about gone. That is pretty much exactly how you'd expect them to age out. If people want these posts to stay on the front page, new posts need to be made
manitcorthe speed of ageout is an adjustable param, the lengthened it significantly about 5 years ago, i would not be shocked if they sped it back up to "normal" speed where the front page could change constantly.
