The script is mine and you are not allowed to leak it. If you do so, you owe me 50 BTC.
What makes you think a non-working script is worth anything, let alone 50 BTC?
If you don't pay up, I'll have to take action myself - and you know what that action is.
When all else fails: blackmail!
If you ask me, the extortion attempt is fake (and a poor fake at that).
According to her
sales thread, she was willing to sell up to 15 copies of the script at 0.99
BTC/each. Ignoring the fact that no one will ever buy the script, she would have earned a maximum of 14.85
BTC.
It would make logical sense for alia to be asking for less than the total she would earn from selling the script via an extortion attempt, not more.
