My main concern isn't with you and I have no doubts about your impartiality, I'm more worried that some bitter people are coming to annoy you by posting inappropriate comments to ruin the contest, which would upset me. But don't worry, that won't stop me from taking part in the chain (I'll just put my BLURT prize back into play for the winner of the next edition if I'm ever lucky enough to win one of the contests).
I'm sure the contest will be a great success, your concept of linking photography and blockchain is original and extremely fun to play.
I understand well what you mean. The problem is that anyone can accuse me and the contest of impartiality at any time, using any pretext. I can't start my contest by banning or excluding users on the grounds that others might accuse me of favoritism. The contest is based on my personal opinion, therefore these kinds of accusations can arise at any time and regardless of what I do. If there are users who want to accuse without knowing the facts, these are the kind of users I hope to stay away from my contest.
Anyway, thank you for your appreciation. I hope to see the participation keeping itself and growing. Have a big nice week :)
