Let us use auto fish farms. They're a good way to make money, and most servers allow them. Autoclickers / hacked clients should not be allowed, but you should be able to tape down your mouse's right click button to auto fish, since there's no modifications made to the game. No script changes or mods, it's vanilla MC and taking advantage of the mechanics and the reality of life. The rules also don't state that it's illegal, so if this doesn't get accepted please add that.
