GET /channels/:channel/follows acting weird

I thought it’s something like that (if it is). Any way to prevent it? (I suppose I can code in some ‘cooldown time’ for each new (un)follower in which any changes of the follow status will be ignored.) And I’ve got another question: Is there any (API or other) way to track followers list updates? (Apart from catching that from the email notifications.) How does apps like ‘TNotifier’ work?

Thank you for the help.
