Like I said before muhamed, the shit you've just put me in and on top of that maybe scamming me then I think it's
I understand and that is the same reason preventing me from paying *now*.
Fair to say you should pay 0.12 BTC for the account and as a compensation. To be honest, I see if its hard for you to pay that but life is though and you gotta fix this.

BTC(~$10) as compensation?! That's a bit high IMHO but if it is normal compensation for issues like this, I will pay you!

Edit:

This could be used to prove that you indeed controled the bitcointalk account once. It is however no proof that you did not stage the hack in an attempt to scam MZ.
For ~20+ days!
What that the price you paid? If anything you could ask MZ to take the account back for the price you paid. I doubt you asked for a signed message either, because you could just produce this now and there would be no discussion.
