Why are certain taunts muted?

In skial servers, certain taunts, such as the dueling banjo and didgeridoo are more quiet than in vanilla tf2 and other tf2 community servers. Why?

It is annoying and easy to spam with just one command, so it makes sense to lower the sound effect.

Not even mentioning that when they are bugged you hear annoying sound all game.
