Milton was well established before that character as Kiki.
Oh fuck, I remember yeah, they were Kiki Chanel, I've got the wrong person then. Look, it's been like a year or two since I kept up with the GTA RP scene, I specifically just remember the robot being a literal silver man, the scientist and him running around on a suped up golf cart and later some jet car iirc. I saw him loads on Criken and Strippin's streams and a few others but they used a soundboard for a lot of stuff such as music and the like.
I'm not saying that soundboards should be actively encouraged, but I'm just saying there's no harm in them if they're used correctly and to the right effect. Make it a rule where if they're misused you can be kicked or banned for it, but don't just kill it out the gate. Maybe give it a test run or something
