I don't know how to feel about these sort of actions. On one hand, they're funny, and it's certainly making it hard for anyone to say the actions of the moderators aren't democratically decided upon. On the other hand, it's still driving engagement with the sub / site, and I rather doubt u/spez cares that people are only posting specific memes, or specific pictures, just that they're posting something and creating engagement numbers he can point to and say "See? We're open for business."
