What do you (assuming you are someone from Imzy, sorry if not) do with spam, when there are no downvotes? Do you have a flagging system, automodding, spam filters, etc.?
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're pretty small right now. They will grow as we do. That's one of the reasons we'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'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.
