It’s unclear when the change would take effect.

The company didn’t immediately comment.

Blocking a user on the platform prevents that user from interacting with an account — such as seeing a user’s tweets or addressing them directly. The blocked user knows they have been blocked. Muting an account, meanwhile, prevents a user from seeing the account’s posts. Muted accounts do not know someone has muted them.

Some users of Musk’s platform said limiting the block function would lead to more harassment on a platform that already struggles to contain abuse.

“The removal of the block function would effectively make harassment an official feature of Twitter/X, taking away what is the only setting that can reduce impact,” Tanja Bueltmann, a historian at the University of Strathclyde in Glasgow, tweeted on Friday. “It is an extremely ignorant and privileged perspective to think that blocking makes no sense.”

Such a change would represent the latest example of how Musk has transformed the platform that he bought for $44 billion in October. Shortly after taking over the platform, Musk restored many previously banned accounts, including that of former president Donald Trump. Last month, he rebranded the company X, with the vision of making into an “everything app.”
