gollark: Since the main limit is the 5 hours you need to keep eggs before abandoning them.
gollark: The egg gathering thing is also more bot-resistant than regular hunting.
gollark: I liked the idea of one user-selected prize per trophy.
gollark: I, a mediocre JS programmer, probably could make an automatic egg getting bot with a few hours of work.
gollark: It's not like it's amazingly hard to make a bot.
