Actually, there is an option in Options of Messenger: "Only the contacts in my Allow list can see my status and send message to me" If you untick this option, another option in the same page appears to be avaliable: "Warn me when others add me to their contact lists" If you untick this second option as well, you won't be notified when new contacts add you, also they won't be added to your contact list, but they will be automatically added to your Allow list. But since you also want to block them automatically, I think some workaround but dunno how to do:

If you tick first option, then the second option you see below appears to be unavaliable and ticked as well. But since it is unavaliable, you can't untick that option. I think, if someone finds a way to alter that second option as unticked, then new contacts are moved to Block list automatically and also you don't get notifications about they have added you.

What do you guys think? Can something like this be possible?
