Pre-mine was an issue at first, one of three involved got away and that's it.
As far as I can determine: The "anonymous" person who "found" the premine and gave it back to the HEX developers instead kept it to himself. This person needs to make right with the whole situation. Or, perhaps he would like me to turn over his identity and name to the community so that he can be forever known as a scammer and thief.
Well, unfortunately - if it wont' go different, that is a logical step. It won't fix all world problems, but would further prove and reconfirm your honesty in all this shit.
Also, for the sake of things being done right, any blockchain proof you might have (wallet ID; transaction, or anything) will add up heavily to the act.
I hate to see that being done like that, but I'd do it if I were you, why lie. I'm personally very much interested in being able to differ between regular people and scammers.
God knows these boards are filled with filth (all grace to the exceptions), so why not name them - it's only right to do.
