Yeah, I certainly don't entirely disbelieve that some ops like that might exist, but it's such a risky operation that it strains credulity to assert there's a significant population of people banging down the doors to do it. Certainly not something that would contribute to supply crunch in any significant way - statistical analysis of house-owning FCs in the past has largely seemed to agree.

Of course, the OP was originally focusing on fully owned wards, anyway, which - like - the first rule of crime is "don't draw attention to what you're doing". But hey, maybe the toothless STF has led to the dumbest generation of criminals ever somehow getting away with it?
