This misleading article was recently published in Canada. CRA refers to Canada Revenue Agency... they are the abusive mental midgets CDN's compare to the IRS of the USSA.

Outside of the preferred method of payment demanded by the perpetrators, this scam has nothing to do with BitCoin. The story, which has been picked up by a number of MSM outlets and is being widely circulated, is nothing short of Canada's media, the Canadian gov., and so-called-law enforcement agencies joining hand-in-hand to perpetuate fear mongering with respect to BitCoin (cryptocurrencies in general).
For those who don't know - CRA scams are commonplace in Canada and the authorities haven't been able to gain control over the situation. CRA scams of this nature have been going on for decades, long before the introduction of BitCoin.
