Twitter asked all users to restrict others from replying to tweets on iOS.

When Twitter’s iOS app is updated, all users can set limits to decide who can reply to their tweets. Twitter has been experimenting with the feature since May, but now appears to be rolling it out more widely. “In May, we tested a new way to chat with the people you want, so you can create a more meaningful change,” says the update disnews on the App Store. “Now, everyone can try this new feature and choose who can respond to their tweets.”

Twitter asked all users to restrict others from replying to tweets on iOS.

To use this feature, users simply click on a box above the keyboard when they write a tweet that says “Everyone can reply.” They can then choose between three options: everyone can reply to their own tweet, only the person they care about, only the person they mention can reply, and it’s important to note that the rule scouring for this tweet is limited to this tweet, and one option doesn’t make this the default option for future tweets.

The feature is one of the more interesting changes on Twitter in recent months, creating new memo-forms of tweets and changing the way conversations are on the platform, as well as a good way to avoid harassment. But it’s also up to users to say that the way they limit conversations feels like a violation of Twitter’s most basic features.

It’s unclear whether the feature is now open to Twitter’s Android app users, or whether it is available to all Twitter users.
