That might work although I have heard some saying that they got a ban instead of help to remove them, I do doubt that a lot 
This I find a really good solution, in fact I less than a week ago recommended a clan of friends doing something like this, I said that they could remove everytthing they can except for 1 foundation and then attach a few others a make a little house of sandstone so there was something for me to check decay status on and report to them when it was safe to come back to the area again, sadly we misunderstood each other, so they removed all the foundations they could, so I cannot check the decay status of their leftovers, only see if it has reverted from landclaimed to available again, it sucks that the building hammer cannot highlight hidden foundations because this seems to happen quite a lot on official servers
