Suggestion - Selective DM Server Settings

This is a fairly simple suggestion regarding large public servers.

I think it would be more intuitive to be able to have separate DM settings for Administrator roles and non-Admin roles. I understand that it would be a bit too complex to add a feature where you can set preferences for every role (Although an interesting suggestion may also be to have a permission for roles which restricts whether or not they can randomly DM people...)

However, when you enter a server with 1000+ people you're expected to have DMs open so moderators and/or bots can contact you if there's an issue, but there's also a pretty high chance you'll get random DMs from members.
Which is why I think it would be helpful, especially if Discord wants to be even more community-oriented, to have sort of selective blocks on DMs when it comes to admins/members/non-roled people.

It could probably help avoid dummy accounts spamming DMs.
