Quick note for new Mastodonians:
If you try to follow someone and get an hourglass, it means they have to approve your follows.
It is not a reflection on you if this doesn't happen immediately. Notifications about this aren't in the same window as the usual "someone followed you" default notifications.
It's not like Twitter's thing. It's Masto's own thing, and some of us are a bit more security-conscious than others, and some of us are slow to review our follow requests.
@sydneyfalk Also some people are really bad at checking the "wants to follow you" bit
If it's been a few days you could send a message, but only ever send one, any more than that could be annoying
this is on the nose
some folks forget to check (or they don't see the emails that result, b/c some people will misuse following for harassment purposes and it's easy to miss a few emails in a flood of 'em)
