Way too many apps implement a hide/mute functionality and then call it a “block”, though.

If I block someone, I don’t want to simply hide their messages from my view, I want them to not be able to see and interact with mine. It should be a restraining order, not just sticking your fingers into your own ears and shouting “LALALA I CAN’T HEAR YOU” while they continue to shout slander to anyone passing by.
