Probably just as rampant. A lot of these appear to be hacked accounts, and that won't stop because people absolutely suck at security. The ones that aren't... well, frankly, RMT exists because RMT is profitable. Lots of people are more than happy to open their wallet in return for eliminating a time sink. If it wasn't at least profitable enough to pay for box price (for 30 days free) then they wouldn't bother doing it, they'd just go to another game.
There is no real way to eliminate RMT without accidentally banning a lot of innocent people, but there are absolutely measures that can be taken to crack down on it pretty severely. Those aren't happening, for whatever reason. Even having a GM cycling through the cities and watching chat for 30 seconds would be effective at this point.
