Tweets promoting a new advertising service on its blog earlier this week, linking three tweeters appeared on the site earlier this year.
However, mock endorsements have been changed, attributing staff members.
An apology also appeared on the marketing web page, acknowledging its error: “An earlier version of this blog post included an image with mock tweets from real users of our platform.”
It went further, explaining its original unawareness of the posts.
Upon discovery, Twitter “took it (the images) down immediately”, the social group said.
The tweets were intended to promote a novel San Francisco product, enabling television advertisements on Twitter.
Appearing to come from three individuals’ Twitter accounts, they did not tweet about it personally.
"What is the song in the new @barristabar commercial? I love it!!," one tweet read.
Another said: "The @barristabar ad is giving me the coffee shakes. Looks so good!"
"Hey @Neil_Gottlieb, @WilliamMazeo, @subhash_tewari – so sorry about the confusion earlier today. We're fixing the problem now," the subsequent apology rang.
While Brazillian Twitter user William Mazeo replied: “Don’t do this again”, Neil Gottlieb from Philadelphia seemed mystified, responding with the phrase: "Still curious how it happened".
