#Mastodon has an interesting feature to mute an account for a few hours or days (I regularly use it when soccer games are on ;).
What would be interesting to have is a time-limited *follow* for accounts. Some new accounts might turn out to be boring bots or post never again. If I could follow for, say, 14 days or a month and after that I’d get a popup asking “do you want to make the follow permanent?” — that would be really cool! cc @Gargron
