Well someone posted some screenshots about it and there was a post some time back at reddit showing someone in GM jail for that. ^^ But I agree there is sadly no official statement on it but I hope that SE will soon post one if enough people are showing that they don't like this situation (and more people reporting them ^^)
Well yes its only a band aid ^^ like most of the housing changes. They could have done this way better but they did not which means that the only thing that they could do now is either 1. ignoring it making people more and more angrier about this 2. make a official statement that this is against the ToS or 3. change the system which means only one house per character and maybe being able to sell the house back to are npc. (For example)
The worse we could do (imo) is just sit here, don't say a thing and hope that they will change it. ^^
And I am sorry, I don't really feel bad about the people that I or others will "hurt" with this. Exactly like how they don't give a damn about the other players by buying and selling those houses, even more since this is such a limited item. But nice to know that its us that have the masochistic tendencies and not those that exploit such a system and showing one of the worse sides of humanity. (Like I said, I dislike this greed in RL too ^^)
