You can restrict commenting on Twitter

Some Twitter users now have a feature to limit the ability to reply to a post. That is, now you can write a tweet and choose who will be able to comment on it: everyone, mentioned users, or just the people you follow.

Testing, testing ...

A new way to have a convo with exactly who you want. We’re starting with a small% globally, so keep your 👀 out to see it in action. pic.twitter.com/pV53mvjAVT

The official Twitter account confirmed that the function is still being tested - a limited number of users can use it.

It's easy to recognize a tweet that you can't reply to - the comment icon below the text simply isn't highlighted. Here are some examples of such tweets from users.

I am glad to see everyone agreeing with me.

Pineapple doesn't belong on pizza.

I'm glad to see that everyone agrees with me.

Lord, finally.

These restrictions do not make the tweet hidden from everyone, but only those whom the author specified in the options when sending (or the author himself) can respond to it. Such capabilities will allow users to better control the communication on Twitter, especially when there is no desire to listen to someone else's opinion or argue with someone.
