Player statuses (Do not disturb)

I play BE and have quite a few friends that constantly spam me with invites. This becomes annoying when I want to play alone or just dont want to join them. I feel like being able to set a status on your profile that stops people from being able to invite you would help. Along with this, I think people you don't have added shouldn't be able to invite you. Strangers add me and then they are able to invite me even though I don't have them added back. Every single person I have brought this up to agrees and I believe this would be a helpful feature.
