We have a report flag on every post and comment to allow items to be escalated and reviewed. Users are required to explain why they are reporting something so that it&#x27;s hopefully not just used as a downvote. (And, tbh, downvotes don&#x27;t really help with catching spam since most of the time they&#x27;re just to show disagreement or make sure comments that aren&#x27;t worth being seen don&#x27;t get seen as much.)<p>We have the nascent stages of algorithms that will help us with tracking spam and such, but those take time and data to become better, and we&#x27;re pretty small right now. They will grow as we do. That&#x27;s one of the reasons we&#x27;re invite-only right now. Dumping a whole bunch of people into one place all at once turns into a free-for-all, and we want to make sure we&#x27;re able to moderate communities to have the kind of quality interactions we want rather than a bunch of circlejerking, and that our technology is able to evolve at the same rate our userbase grows.
