Users of X, formerly known as Twitter, will no longer be able to block comments from unwanted followers, according to a post by X owner Elon Musk on Friday, eliminating what's long been viewed as a key safety feature. "Block is going to be deleted as a 'feature', except for DMs," Musk wrote Friday. The mute feature just keeps the individual user from seeing the undesired responses, but doesn't eliminate them from others' feeds. Twitter users have also long employed the block feature in boycotts and to avoid seeing ads from specific brands or promoters on the platform. Binance CEO Changpeng Zhao, an investor in the new Twitter alongside Musk, said in a post that the company should focus its attention elsewhere.
