But they don't, that's the problem. For some reason you can report obvious ToS violations till the cows come home, but SE will not read and/or act on them. Their solution to these people abusing the system is to change the system to try to stop them. But humans (being ingenious when it comes to finding ways to exploit things for money) will always find a way around any new obstacles you toss into their path.
I'm not saying don't take these measures to combat housing cheats, but like... translate and read the reports people send in, investigate them, and actually remove the problem players, too.
Also trial accounts can't participate in the housing lotto as far as I know.
