A mod will read down through the user's posts. There is a predictable pattern. As a general rule, they will start out with reasonable, under-the-radar comments until they get enough karma for their comments to appear on the board. After that, all bets are off. When you see trolling, shilling, black-pilling, dooming...it's a good indication that they don't belong here -- be it bot or human. If in doubt, deport and we'll make the final judgment call.
