If an account is not associated with a phone number, changing the display name to that of the SpaceX and Tesla boss will mean it's immediately locked.
As The Verge reports, the microblogging site will then ask the user to pass a CAPTCHA test and providing a phone number to regain access to the account.
In a statement, a spokesperson told the publication: "As part of our continuing efforts to combat spam and malicious activity on our service, we're testing new measures to challenge accounts that use terms commonly associated with spam campaigns.
"We are continually refining these detections based on changes in spammy activity."
The company wouldn't confirm or deny whether the measure has been put in place for other public figures.
What is known, though, is that it's possible to confirm the authenticity of your profile, and actually keep your display name as Elon Musk.
This comes down to the fact Twitter is battling the countless bots on the site which are being set up and imitating the businessman's profile to scam users into replying.
