The website is a big scam. It is not at all for knowledge sharing. They create fake popular Quorans by cteating robot accounts just ment to follow and upvote. They sell you a dream of fame. Trolls are actually backed up by moderators to do their unofficial job. The moment you crack and abuse a troll, the mods will through their useless policy at your face and ban you. Its a big scam just to sell ads and earn profits. Please stay away from it at all costs.
