Sounds if this is sort of a suggestion on who it is. Did you recently learn linear regression?
Lol, no. I used to play with it on my old Casino programmable calculator in school, but not since.

Wasn't the attacker on PD only able to withdraw 40 btc before his misbehavior was noticed and all his other withdrawals were blocked?
