Polo can claim an enormous quantity of lumens just signing his coldwallets with BTCs that belongs to his users. That´s a really nasty move of his part. It would be intelligent for the Stellar team to not redeem that lumens. Do we know the coldwallets addresses of poloniex?
Stellar cannot do that : the rules are the same for everybody : you control a Bitcoin address, you get the XLM.
Use your own wallet next time... or not i you want Poloniex steal you one more time (the third, exactly : it was the same for the first distribution).
