I recall a recent problem on another FT Forum, possible HHonors, regarding a guy who did a quiz or something quite a few times for himself and his parents, all from the same ip computer. Then, wham, the 3 accounts get frozen. Then he complains that it is because he is Chinese and being discriminated against..... forgetting for a moment that maybe there was something "interesting" in what he was doing.

Phantom accounts.... It is interesting that not only will some people be dishonest, but will also want to brag about it on FT.
YMMV. Your Morals May Vary
