Although only verified accounts had their images swapped with other verified accounts, Twitter had to disable profile settings for all its users in order to contain the problem.
Over 500 million Twitter users were not able to change their existing settings. But only people with verified Twitter accounts had to see their own tweets next to someone else’s photo.
Twitter publicly apologized on their Twitter support channel: “We have temporarily disabled profile settings changes for all users. Our apologies for the inconvenience. Thank you for bearing with us.”
