Bitcoin Porn Blackmail Scam Moved to Poloniex Wallet

3 Comments

When reports of this email scam first started appearing last September the perpetrators were discovered to be using a Matbea wallet. That appears to have changed. On May 30 every output transaction from hundreds of reported blackmail scam addresses went to a Poloniex wallet address.

These bitcoin addresses were reported as scams related to the porn blackmail email:

Each of them shows an output to 1E2J2DAFGToqmTxK5H8fG6V3Tp3xqSiAm4 on May 30, 2018.

A quick investigation shows 1E2J2DAFGToqmTxK5H8fG6V3Tp3xqSiAm4 is among the Poloniex wallet cluster.

2,759 BTC Burned All-Time
The total amount of bitcoin in circulation decreased by almost 9 in 2017 due to “burn” addresses. Burn addresses, like the Genesis Block, are deadlier than “zombie” addresses, because there is no chance of coming back once BTC is sent to it. There are almost 400 known bitcoin burn addresses, i.e. valid addresses with no private key, to which, for a variety of reasons, people have sent 2,759.42507135 over the years. In 2017, 9 of these addresses received 8.97140133 BTC. That is way down from 2016 when 26.04 BTC was burned. Continue reading 8.97 Bitcoins Burned In 2017 →
