So, what is a followbot? It certainly seems as if they're bad, but I'm not really sure what they do or the purpose they're supposed to serve

zac's answer is correct. basically, the only way for a user (say mr. moonfire) to show up in a different mastodon instance is for someone from that instance to follow him. then, the new instance knows to look for messages from him and drop them into the federated timeline.
automatic followbots are combing around, linking people to instances. it's not for bumping up people's follow counts.
