San Francisco, California - Twitter will permanently suspend users who impersonate authentic accounts on the social media platform, new owner Elon Musk has revealed.

"Going forward, any Twitter handles engaging in impersonation without clearly specifying 'parody' will be permanently suspended," Musk tweeted.

"Previously, we issued a warning before suspension, but now that we are rolling out widespread verification, there will be no warning."

Musk also said any name change at all will cause temporary loss of the verified checkmark.

The move came after the platform allegedly suspended users who had changed their usernames to Elon Musk, including comedian Kathy Griffin and actor Rich Sommer.

After Griffin's suspension, Musk tweeted that she had been banned "for impersonating a comedian."

"But if she really wants her account back, she can have it... For $8," he wrote.

Musk completed his $44-billion-dollar takeover of the platform last week, immediately cutting the workforce and implementing a monthly subscription fee for users to be verified on the platform.
