yup! I may have OCD of consuming as much info as possible including unfollow! A list with toggle buttons at notification setting might be a good way to balance.

Maybe with a widget that suppresses a push, if the follow is within N time period after the last follow from the same account? That could filter out most of the accidental follow>unfollow>follow stuff. Follow spam has apparently been an issue in the fediverse, and connect request spam in XMPP.
