Group Chat Dm's/GC Privacy Settings or Invites

I feel like there should be a option in settings so that people cannot randomly add you to group chats without consent or at least send you an invite to a group chat.

People can continuously add you to Group Dm's even if you don't want them to, and there is no setting or function to stop them from doing so.
I personally have a experience of being added to an attack group chat which I continuously kept getting added to unless I blocked or unfriended the person. It would be nice to get a invite to the group chat like a server invite or a feature to turn off people being able to add you to a group dm if they want to.
 This should be a really important feature. Please let discord recognize this.
