Coming up at some undisclosed point in the future, we will be enabling auto-ban by ratio. If your ratio drops too low, you risk losing your account. Now, before you get too worried, this is only going to target those people specifically leeching huge amounts and refusing to share back. These are the kind of jerks that make it hard to get older (as in, anything past about a day around here) content since they just hit and run. New users have nothing to worry about. Even users that have trouble sharing back to 1:1 have nothing to worry!
