No kidding around, this is great plug-in to stop scammers. It does not prevent scams such as dice duel scams or gambling scams, but it still prevents the majority of the rest. The only thing I'm concerned about is how easy it will be to implement it, and how newer players will be able to use it effectively.
Maybe a tutorial on how to use it correctly for an x amount of meebles, such as how Mineplex's is like.
