I agree that bots shouldn't spam content, but help people on command, like the TL;DR bot. But why was Reddit garbage? Was it for its bots, or was it for its toxic environment? Because, in my own opinion and experience, bots weren't a big deal over there. Instead, who was the brave enough person able to comment and face all kind of shit just because his/her comment?
Don't ignore the whole garbage hiding under the carpet half of it and expose the other half to the people claiming "I don't want this filth."
