Wanted posters would be very very cool! Small trouble in that scammers can always just log off when caught, or go into Peaceful mode and be invincible...

Rating:
1) When giving a rating, it is weighted by your own rating. A 100%'s rating counts twice as much as a 50%'s rating. Good people who proved themselves trustworthy count more than bad people.
2) Your rating is the average of all ratings given (weighted by their percentages). This means if 4 100% people rated you 100% and 1 100% person rated you 0%, you only go down to 80%. If that person was a 10%, you only go down to 97%.
3) You only get to rate once a week at 50% - twice a week at 100%, once every 2 weeks at 0%. This means you can't just run little fake tradings for 0 plat with your buddies to raise each others' ratings.
4) Optionally, you can only rate someone once - but really, if you have a rating limit, you're not gonna waste all your ratings on the same person over and over again.

If I can rate the people who scammed me, and especially if a low rating makes things harder to buy/taxes on main higher, I will be happy.
