Is there a way to block contact yet?

Much needed, I'm getting inappropriate spam text messages thru the dashboard. Would like a better alternative than just DND

I recently had some spammer block a whole bunch of appointments in every calendar I have available.

Please! I get the same spam filing multiple times per day.

I would add to that Calendar booking, although I suspect that would be covered if contacts can be blocked from forms submissions.

Yes! This is very much needed.
