while I'm at asking noob questions: What is it with all those follow/federation bots that keep following me? Is this just technology made visible, or are they scanning me to determine if I'm a spammer?
@dredmorbius seems to sum up the potential problems pretty much though.
For me personally, this is less a problem, because I am not very private on social networks.
I know folks who have different needs though and can see them being pissed off at such things.
