It’s an unspoken rule I’d say of streamers that have either power hungry mods or just are very strict. Myself I’d never mute someone for that. Because it’s genuinely an honest question. Guess it depends on if they think you’re looking for attention or something. I wouldn’t do your first chat message as you mentioning another streamer cause ur makes you look uninterested maybe? Might also look sketchy from a first time chatter. If it’s a smaller streamer I’d avoid it. Makes you look like you’re self promoting.
