The character of some of the men involved aside (do spammers have any character?)...
This will be a very interesting case for us Canadians in the porn biz. It may even go to the Supreme Court of Canada.
Will the Canadian government extradite Canadians to the US for doing something involving freedom of expression which is perhaps perfectly legal in Canada? (I'm not familiar with the details of the content in question, but if it is just BDSM, and/or fantasy role-playing, then it may be legal in Canada, a la the Sweet case).
The Supreme Court of Canada takes Section 2b of the Charter of Rights, the section concerning "freedom of expression", very seriously.
There is some precidence suggesting that this would be a question the Supreme Court might want to consider; accused murders are no longer extradicted by Canadian authorities to the US unless there are guarantees that they will not face the death penalty - the death penalty is considered a violation of a person's rights under the Charter of Rights portion of the Canadian Constitution.
US Federal prosecutors know this and I suspect are looking at this case as testing the waters when it comes to extradicting Canadians on obscenity charges - a pure freedom of expression issue, not as serious as the death penalty to be sure, but still a Charter of Rights issue.
This could be one of those precident-setting cases for Canadian webmasters, for better or for worse. We'll know where we stand in about 8 years or so.
Justice in Canada is thorough but sloooooooow.
