System for friends and blocked players

It would be good to have a sort of contact book or friends list within the game, on the home screen. Players you meet in game sessions who have stood out for their positive behaviour and team spirit should then be able to be added regardless of their alliance, and you should be able to invite these players directly to new game sessions once you have joined one yourself. The recipient must confirm the request to add them to your friends list.

At the same time, it should be possible to block fellow players, who would then also appear in the list as blocked players. Diplomatic functions (messages) within the game session should be disabled for both parties in the case of blocked players. This also applies to the inbox on the home page. Blocked players in a shared game session should be highlighted within the session, or a warning message should appear stating that a blocked player has joined the session.
