We could try tracing the transaction if it hasn't already gone through a mixer, but it probably has, and whoever wins will probably be an alt account and will spend it of his/her own accord You can't really control this kind of stuff, you can only hope. I'll return the coins if I actually win, though, which is probably not going to happen. Funny thing is, the first few letters of the address is BFXSux; pretty sure this is actually from bitfinex or some other exchange, but i'm sure it's actually BFX.
