I've previously complained on here about receiving "reaction" notifications from Apple users in MMS groups
I am happy to say that I have found a workaround on Android:
The `AutoNotification` application (part of the `Tasker` ecosystem) is capable of doing *exactly* what I wanted: blocking notifications from my messaging app based on regular expressions.
This pattern covers most of the notifications that grate on me the worst in my family's group chats (where the ratio of reacts to real messages is usually something like 10:1)
`^(Loved|Liked|Emphasized|Laughed at|Reacted . to) (“.*”|an image|a movie)$`
The upshot of solving the problem like this is that I can also squelch notifications from other applications based on other patterns. Well worth the $2.49.
