Interesting.

So "Maria" has 1000 btc owed - for charity to (awwww what a nice gurl).
She amusingly demands interest of 60% (I  assume to help out those charities)
Makes thinly veiled threats of violent visits (strange for a charitable person dont you think).
Refuses to log a claim and supply personal information.

The amount of money ($6000 AUD) is only worth a single paid violent visit to an individual (I have my contacts).
You would never announce you are having someone come over to persuade if you were indeed the type of person to organize this.

My guess Maria = Butt Hurt silk road seller trying to pretend they have some clout. If 5k has impacted your drug business at all you are essentially powerless.
Maria is hoping to reclaim her drug money, but is unable to provide the ID needed to do so, so here she is making public hollow threats.
