<human>: Give me a shortened version of the text

Throwaway for obvious reasons. I have received an e-mail from PayPal on 10/06 stating that I had sent a payment of $40 USD to an "Andrew White". Since I have no idea who this is and I have not purchased anything via PayPal that day I was suspicious straight away. I reported the transaction and made sure to change my password & secret question/answer combos (changed my email password too). I also made sure to phone PayPal to express my concern that this is a fraudulent transaction. They said that it would take 10 business days for them to investigate. 

Today I've received an e-mail from said "Andrew White" that contained the following:

*Subject: I want you to pay very close attention to this*

*You will notice in the following link a list of bitcoin scammers.  I want you to notice the name, home address, and pictures of a prominent scammer.*

*I want you to immediately lift the hold on the payment of $40 from my paypal account or you are next.*

*

*Thanks*

I did follow the link to the google doc and could not make much sense of it. Judging by the amount of "Anonymous" viewers on the doc I assume this was a mass e-mail.

The doc talks about something to do with "bitcoin" which I found out after goolging is some sort of online currency. I have never heard of "bitcoin" before this e-mail.

I am very concerned as to what this scammer can do as he has my full name and PayPal e-mail address.

Who can I alert to this? What authority can help me?

P.S. I am in Australia.

I can upload screenshots of the e-mail/paypal transaction if these can be of any assistance.
<bot>: Someone used my PayPal account and authorised a $40 USD transaction, I changed p/w and reported transaction. Now the scammer is trying to blackmail me into unfreezing the transaction. I need help!
