Make cheermotes unavailable for blocked users
Currently, cheermotes are available even for blocked users who unlocked the emote before they got blocked.
This, however, also allows for harrassment outside of the channel of the stream who blocked them. They can go to channels of streamers that the streamer is acquainted or friends with, and continue to harass simply by intentionally using their cheermotes.
I don't think this is something a streamer should have to deal with, and therefore I think that while a user is blocked by a streamer, they should also not be able to use the cheermotes, just like they're not able to subscribe to a streamer and use the sub emotes.

This is a fundamental thing to prevent trolls and harrassment. Good call CaveMobster!
