Calling it an "extortion attempt" I think is a little ridiculous - but whatever (funny how one silly mistake overrides over a year of holding 250 BTC which was held at the time that BTC was approaching its all time high - the initial return of 200 of that 250 was because I was actually worried that someone might try and locate me).
I do understand that it was just a temporary lapse of judgement, though it was extortion by definition. You were trying to get your way by threatening the forum with monetary loss.
Regardless, it was very noble of you to accept your mistakes, apologize, return the
BTC and still contribute to the forum as you do. I don't think anyone holds your mistake against you anymore.
