So...I just tried a fake SMS generator and attempted to use it on the JCS website for the giveaway - and got an error: "Phone already used"

Not going to use my real number or attempt to fake it again, for science's sake. As proof, my JCS address is 1Bup3X6n2VQbtagtTqAyNW5ikNyCT4z1y9

This means phone numbers are being spoofed out the ass so people get a larger share of this coin unfairly.

OP, either you accept this willingly, or need to change your distribution method ASAP.
