New reply limit option available to everyone
Elon Musk says that the new control option will be of great help against spam bots. It seems like we will see less irrelevant spam posts appearing under almost every post.
Twitter first implemented the response limitation control in 2020. Users could limit their conversations to only the accounts they follow or the accounts they mention. However, at that time this setting could only be selected before shipping. This feature has been changed in 2021 to also be set after the post is shared.
can be abused
The newly announced feature has a significant drawback; The new reply limitation feature can be misused to spread misinformation. If an account posts misleading information and adds the restriction, verified accounts will not correct it in replies. Although quoting is available, the incidence of responses is higher.
