I always did it if the wind was acceptable - because it made it easier to push in the hangar. If there were people in my spot i'd land somewhere else. Obviously you should look at your landing site and behave accordingly. If theres a danger of some young children jumping into the tail rotor then face them obviously.
Very rarely do you see unaccompanied children at airport parking areas, so its not usually an issue.
Accompanied ones will always be grabbed and held tightly by overprotective parents.
That just leaves the adults. Most have common sense. Anyone one who sees a VERY noisy machine with large spinning blades beating the air into submission, who then runs wildly towards the tail rotor with their arms flailing - deserves everything they get.
I think that Darwin bloke was onto something....
