There is a player that continues to harass me with that damn Space Channel 5 emote ever since the time they spammed it during a PSO2 concert months ago (I was one of several people who report spammed them because of that), it is now to the point every time this person fires off that emote near me, I report them.

If you can hide accessories on blocklisted players in the settings, making it so you can't see their chat (both text and cut-ins), and preventing them from being in a party with you, then it shouldn't be that hard to mute the audio of their emotes.
