[Danger] Are Private Twitter(X) Alt Accounts Safe? 5 Reasons They Get Exposed

Many people create an "alt account" (sub-account) on Twitter(X) to vent their true feelings or complaints. Assuming that they will never be found out if they make it a private account, many people post extreme remarks and personal secrets.

However, in reality, troubles such as "my private alt account was discovered by a colleague or friend" are endless. In this article, we explain the 5 causes of why a private alt account gets identified and the definitive countermeasures.

1Cause 1: Contact Sync Feature (Appearing in "Suggested")

One of the most common reasons an alt account is exposed is synchronization with the smartphone's "address book (contacts)".

If you unconsciously allow "sync contacts" when installing the Twitter(X) app, your alt account may appear in the "suggested users" of acquaintances who have registered your phone number or email address.

Even if it is a private account, the existence of the account itself is displayed, so people may guess "Isn't this so-and-so?" from the icon or profile text.

2Cause 2: Linking via "URL (Link)" Sharing

Have you ever found an interesting tweet and shared the URL with a friend on LINE, saying "Look at this tweet!"?

Actually, when you copy a sharing link from the Twitter app, parameters that can identify your account may be attached to the end of the URL (specifications vary depending on the time). There are cases where friends who click this link realize that the original linking user is your account.

3Cause 3: Reusing User IDs

Are you using an ID for your alt account that is similar to what you use on your main account, other social networks (Instagram, TikTok, etc.), or as a game screen name?

If you set an easy-to-guess ID like "@RealName_ura" or "@UsualID_sub", acquaintances may find it when they casually search for it.

4Cause 4: "Background Reflections" in Posted Photos or Images

It's dangerous to let your guard down and think, "Unlike text, photos won't expose me." There are many cases where individuals are identified from the scenery out the window of their home, the distinctive wood grain of a desk, the pattern of a pet, or photos taken at a frequently visited cafe.

• Landscape photos posted along with complaints about the commute or workplace
• Photos showing the same clothes or accessories as the main account
• Posts showing the same location history as the main account, like "I went to XX today"

5Cause 5: Information Leaks Through Followers (Screenshots)

Even if you only allow a few people you trust to follow your alt account, you cannot rest assured. Even if it's a remark inside a private account, any of your followers can easily take a screenshot and leak it outside.

When a friendship becomes strained or an extreme remark causes resentment internally, the worst-case scenario is that the screenshot is sent to an anonymous message board or people related to the company along with your real name.

Before it's too late! The most reliable countermeasure is to "Erase the Past"

Even if you think "I should review the settings of my alt account" or "I should clean up my followers," the past risks of things you've already posted (complaints, abusive language, leaks of confidential information) will not disappear.

Rather than continuing to use social networking sites with the anxiety of not knowing when your identity will be revealed, we strongly recommend using X Deleter to batch delete your past posts and reset the risk itself.

Throw away the assumption that "it's safe because it's a private account" and clean up your digital footprints right now.
