Elon Musk has unveiled a new rule for everyone with an account on Twitter to follow. On Monday, he tweeted: "any Twitter handles engaging in impersonation without clearly specifying ‘parody’ will be permanently suspended.”

In a follow-up tweet, Musk said, "Previously, we issued a warning before the suspension, but now that we are rolling out widespread verification, there will be no warning.”

The update sounds abrupt from the person who a few days ago tweeted, "Comedy is now legal on Twitter” after taking control of the company.

Comedy is legal — as long as it follows the rules, which are whatever, Elon says, adding that those rules could change at any time.

Ever since Musk promised his Twitter would bring "power to the people” by offering verification to anyone willing to pay $8 for a subscription, some owners of already verified accounts have been renaming themselves Elon Musk, highlighting the issue of a verification system that doesn’t actually check who controls an account.

According to The Verge, comedians Kathy Griffin and Sarah Silverman are among the accounts already known to be locked or suspended as a result.

Twitter’s existing policies already contain a section covering "parody, commentary, and fan accounts.”

Musk later clarified that the plan is to go with the heaviest penalty on the first offense, skipping the first two levels of enforcement listed on the current impersonation and deceptive identities.

Despite his earlier statement that no major content decisions would come down until Twitter put together a content moderation council to vote on them, the service’s new owner has made this ruling, apparently, all by himself.

The Twitter Terms of Service don’t reflect any new rule changes, and Twitter has not responded to an inquiry about how its policies have changed, reports The Verge.
