"Do not disturb allow and silence notifications the same thing?: All I wanted to do was block some people from messaging me when on do not disturb and had them both on silence and allow whenever u put them down for just one singular one. And then when you try to change the setting you don’t want it deletes the opposite one. For example if I put my friend down as block when in do not disturb it will put him down for block and allow and when you try to take him off allow and it takes him off block too. Any help?"

Blocking Messages:
A. Using the App Called Bouncer:
For text messages, there is an app called Bouncer, which block messages out by keywords. But, if these are not text messages, then is would not be an option. Here is the link: Bouncer: Text Messages Blocker 4+ - App Store
B. Use Malwarebytes Mobile Security:
The free version blocks popups. The paid version blocks out known spam numbers, lets you add number to the block list, and allows you to report these numbers to the Developer. So, consider using it.
