Asking to play/or playing a soundboard is against TeamSpeak TOU Rule 11:"11 - No Voice Changers / Soundboards / Excluding the Alienware SoundBlaster Pro Voice Changers"
In this regard, Xnator had a reason to ban you if you kept asking for it and asking somebody to micspam to play a soundboard breaks both Rule 1 and Rule 11 of TeamSpeak TOU.1 - No micspamming.
11 - No Voice Changers / Soundboards / Excluding the Alienware SoundBlaster Pro Voice Changers
Xnator has done nothing wrong here. Define micspamming, it can be me talking really fast and people will say it's micspamming
