You haven't yet done so despite being told to update your signature by massage. So you are disqualified from the campaign.
October 18, I got accepted (have learned it thru PM).
October 19, yesterday. I updated my avatar and signature campaign (I've sent a PM on that day).
October 20, received a PM that I was late in updating so they removed me.
Not a big deal to me that I got removed for a valid reason since that was your rule. But that was an unprofessional approach. Even famous CM and BM's are not like that. Not interested in joining anymore. Good luck with your campaign.
Notice- Today is the last day of wearing signature and avatar. Those who will not update till today, He/She will be disqualified
