It seems like most instragram users have over 100 followers[1], if they&#x27;re all active and connected that means a sizable chunk of likes (or whatever else you can do) when you post something.<p>Surely sending all these notifications isn&#x27;t entirely free - someone else posted Snowden receiving 47 gigs of mail because of email notifications.<p>You could do something like send notifications with some sort of back-off.  Send them for 10 seconds, then back off to a minute&#x27;s worth chunk, then 10 minutes, then an hour.<p>Then again, I don&#x27;t have any statistics on how much these external services actually cost, nor how often this actually does happen.  Simplest thing is for instagram&#x2F;twitter to not care, and to point the finger at apple&#x2F;android and tell them they should have UI to squelch high-frequency notifications.<p>[1] <a href="http:&#x2F;&#x2F;www.statista.com&#x2F;statistics&#x2F;419326&#x2F;us-teen-instagram-followers-number&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.statista.com&#x2F;statistics&#x2F;419326&#x2F;us-teen-instagram-...</a>
