Could someone please make an updated rules list that explains limitations relating to redstone mechanisms and mobs/farming, or if there is a list, could it please be pinned? It would be nice to have a concrete list saying how many entities can be in a one block space or a given amount of space. Also, what kinds of farms are allowed and what are not (charged creeper farm or farms using a lot of redstone that could lag the server.) I know some mechanisms can put quite a load on the server like an auto sorter or a long system of hoppers. I can't think of every single limitation but it would be nice to have a good portion in advance before starting a complex and time-consuming build.
