He's far ahead from doing it on purpose, I already told him to stop and he kept SCREAMING. Only when I asked him to keep quiet for the 6th time he cooperated.I checked the 2nd demo and -yes, the guy is kinda on thin ice, but- I wouldn't consider it micspam as well.
@Madact I agree with you thinking he's not doing it on purpose. I suppose more evidence is needed.
