.@instagram can you please let us know why so many people randomly had their accounts disabled tonight due to "terms of service violations"?— Tara (@FabulousButEvil) May 24, 2013
UPDATE 2: Instagram has responded with the following comment.
A small percentage of users could not access their accounts for a few hours as a result of a temporary glitch. We have restored access for these users, and no pictures or data were lost.
It seems many Instagram were caught off-guard today when the free photo-sharing app suddenly deleted a significant number of accounts, citing “terms of service violations” as the reason despite many affected users having no such content on their profiles.
