Many servers dont allow bots. And a lot of the users who think they need a bot really dont. And of course there are many whose sole purpose is to annoy in one way or another or in general cause probs. Like anything else, its how they are used that makes the diff.
That said, would i give up my lil bottie or our channel bots? Nope. They are set up to do too many things that make my life easier. Sides, im rather fond of them
