One of the most annoying things on the social network Facebook — when you accept a request to add friends or accept your request, Facebook Messenger also appears alerting that you the user in touch even in the messenger.
As a result, have to exit the Facebook app, go to the Messenger app and open this automatically created a dialogue to clean it up. Some users have to go through this ritual a bunch of times a day. Now the developers Facebook admitted that it might be a little tedious.
Of course, just noting these alerts would be too easy. Instead, Facebook used machine learning to keep track of the user’s response to them — if he uses the opportunity to welcome a new contact. If the user rejects them, then these alerts will cease to send him.
