Not happening, a lot of mutes are because of people breaking the rules in messages (ex: suicide encouragement, spam, toxicity.)
Also really not sure what your point is with the mute, you got muted and it was a fair mute but then you got banned?
Try contacting support, I don't think I can really help much personally, sorry!
