The twitter account for Alexa Dell, daughter of Dell founder Michael Dell, has been deactivated following security concerns prompted by her detailed account of the family's whereabouts.

The security of the CEO, who expects to spend $2.7 million in 2012 t0 keep his family safe, came under question after an photo of Zachary Dell was posted by his sister Alexa on photo-sharing app Instragram, according to Bloomberg Businessweek

The teenager shared a photo of Zachary devouring cuisine in a private plane on a trip to Fiji. But, that's not all, the magazine reported. Like millions of others who use social network sites, she would often-times detail the time, date and location of many events attended by the family, including trips to New York City and a high school graduation dinner, according to Bloomberg Businessweek.

The photo has since been removed.

After Alexa posted the photo to Instragram, it would eventually pop up on the website Rich Kids of Instragram, a tumblr account dedicated to showing the way people reveal their wealth on social media.

Since many users have their Facebook account or Twitter accounts connected to the application-recently acquired by Facebook for $1 billion-it's often easy to track additional social media information from users. A Twitter account and Google+ account purported to be used by Alexa has since been taken down.

Michael Dell is a self-made billionaire. At 19 years old, Dell launched from his dorm room at the University of Texas the hardware company that would reach a $20 billion market cap. The father of four has a net worth of $15.9 billion, according to Forbes.

"We don't comment on Mr. Dell's or his family's personal activities," a spokesperson for Dell told ABC News.
