I don't think people would be ok with voice chat being just micspam and no talking, except for very rare occasions maybe, and even then it's unlikely.
When I say "if the server seems generally ok with it" i dont mean if 60% of the server is somewhat enjoying it and the 40% of the server fuckin hates it, i mean if literally everyone is enjoying it except for at most maybe like 1 or 2 people who are ass pained for no reason (because we know anti-fun people exist, even if rarely), which might not be the case most of the time, in which case you would mute the micspammer based on the reactions of the people who are on the server.
