Facebook has confirmed that it is working on a 'dispensing key' similar to the one on the Reddit platform, and that it is testing 5 percent of Android users in the US.
Facebook indicates that this key can be used in shares and comments; attention to the fact that their purpose was to detect uncomfortable content.
It was announced that users will be able to use the exclamation key for content they do not like, and then encounter a list where they can explain why they made the decision. On this list, Facebook will be notified that the content is 'aggressive' or 'misleading'.
