Expired and frozen RM profiles

[+ bcbg1205]

In my city I am suddenly noticing that at least 40% of the RM profiles on the site have expired or are frozen. Expired profiles: some have been expired for a few years. I wonder why they leave them up. Frozen profiles: I wonder why they are frozen. On vacation? Just taking a break? No longer need the income? 

And then there's PNP, a red light for me. When I add together the expired and frozen profiles and those that list PNP, the options in my city have dwindled compared to just a year ago.
