The Atlantic met een artikel over tieners op Instagram:

When teenagers are planning a big party, they’ll sometimes create a new Instagram account, often with a handle that includes the date of the party, like @Nov17partyy or @SarahsBdayOctober27. The account will be set to private, and its bio will list the date of the party and sometimes the handles of the organizers. Sometimes it will include stipulations—for example, if it follows you, or approves your follow request, you’re invited.
