Well, I got -2 votes for my own promotion, I still don’t know who they were and what their concerns :),
But I can ask members of our team who gave me +1 votes, “Did you regret giving me +1 votes by any chance?” and I wish that it would be “no” 
so @kumaraditya303, Welcome to the team, and please prove my concerns were wrong. (I am not in -5 vote, but I published concerns to the public.)
