The algorithm for hot is really toxic. As a community gets bigger the content that more people review and engage with is the simplest of content such as pictures and Memes and it comes to completely dominate a sub past about 10,000 users. So communities have to create rules and consistently moderate such simple content out to maintain a baseline of quality which always expels the highest quality longer form content.
