well, you aren’t //supposed// to do anything. but a lot of people do. some people make videos, or do give away that are like “300 followers giveaway!!111!11@#!”, or you can idk make something for your followers, or take a few writing requests if you’re a writer
it’s whatever you want to do, and if you want to do it.
whenever i reach a new thousand or w/e, i usually make a post and just say thank you because y’know, no one //has// to follow you, but they do it anyway, so it’s nice to say thank you once in a while.
