And yes, I definitely know they were probably on their best behavior, although I was really surprised at the number of places I went to see where the tenants were really rude and not at all people I would want to rent to.   

Most brokers and salesperson that get into trouble with the State Real Estate Commission because: (1) they have a conflict with a consumer; and (2) the consumer reports the behavior to the Commission.

@Noah FarleyZillow displays them.

Would this "advertising-like" behavior be in some sort of violation of some Law somewhere? 

For example, the broker name and fair housing logo must be included, and have display guidelines.

I mean it seems to be the right kind of place because at night you don't see questionable behavior, i.e. prostitutes, drug deals, etc.

@Jim K.It's like being upset with your child or dog for bad behavior.

We end up recycling the same bad tenants, rewarding their bad behavior, because some cheap landlord wouldn’t pay the $71 to get a judgment and/or possession.

Or the "Feel the Burn" stickers you see proudly displayed on many Portland bumpers, you resent people who buy rentals instead of Red Bulls.

@Jeremy BartlettGo talk to them and lay the law down If they continue theIr bad behavior then post a comply or quit document up
