All true, but note that the "other 18" in this case are not all posted in the same week, with all caps etc. Several are in the same week, but others are spread over multiple years and are not overly gushy, all-caps-y, or anything else (although it's possible they were one-time posters). Reading through the filtered posts, my thought was that if these were the work of someone gaming the system, that person is A LOT more subtle and meta than one would normally expect. More likely is that the majority of them are totally legit.
