[Feature Request] The ability to turn off all DMs including friends.

With some bots claiming to give "Free Discord Nitro", in which if the user joins a server then said server turns out to be a NSFW server, myself and others have been thinking of a feature request. The ability to turn off all direct messages including messages from friends. People are creating more and more bots that are programmed to scam the user into joining an NSFW server. Blocking those bots could become a hassle, if you’re getting scams left and right. The idea is to have an on/off switch in Discord User Settings that would allow the user to turn off all direct messages. Even if the user isn’t being scammed, there are other uses for this feature. If a user decides to temporary block another user, they have to re-friend each other. With the feature I’m suggesting, you can “block” other users (if the user got into a fight or something) and not have to re-friend them. 

I'll attach a screenshot of what it may look like when said screenshot is ready
