You mentioned that you've never been counted in a census before. Well, I've been through a census experience and it was a good one. Now, on the topic of whether census is possible on Steemit, I totally think it can be done! It would require some coordination and the green light from the platform bosses, as you rightly mentioned. But if everyone's on board, we could count each member, moderators, and administrators in every community, making sure not to count someone twice. Teamwork makes the dream work! I wish you the very best in the contest! 😊
