I am going to have to disagree with what is being said in this thread. Firstly I have never used CL to find SPs or MAs, but I realize a lot of people did use it, and even many of its detractors here admit that it was not all bad.
The issue, as I see it, has nothing to do with economics and much more to do with the fact that it was shut down by government pressure to make a "statement" about sex work in general. They trotted out the same arguments they have been making in the Bradford case. For the most part they are lies and exaggerations designed to create moral outrage and win votes from the unthinking or unaware populace. They paint all sex-workers and the sex trade as seedy, overrun by lowlifes and criminals.
Remembering the differences in US and Canadian prostitution laws, (it was easier to shut down in the US) they had to make the case that CL was overrun with exploited children, human traffickers, and the slave trade; and those that read it were using it to stalk and do harm to the sex-workers. That is outright BS, but it plays well with the Soccer-moms at home reading about it in the Globe.
If anyone thinks that a stalker or someone who is meaning to do harm won't use newspaper ads, boards like this, or advertising sites like E-C or others to find a victim then you are mistaken. There maybe a bit more security, but not enough to stop someone who is determined to do evil.
As for the Human trafficking angle, not all of those cases involve people being forced into sex-work. In fact I would wager there are a lot more people being exploited into sweat-shops, domestic work, and other low paying jobs than those forced into prostitution. I would say a much higher percentage. Why are they not being looked at by the government? Because it costs them votes in the various ethnic communities. For example, just look at the last two boatloads of people from Sri Lanka that landed on the west coast. From what I saw, there was a large number of men and families in that lot. Not a lot of people who could be exploited in the sex trade. Why are they not tackling that problem? Because it will cost them votes with various communities.
In my opinion this is the government starting to fire back after having lost the court case in Ontario. They know they have a losing argument from a legal and ethical standpoint, but that they can win in the court of public opinion if they approach it right. To hell with the truth, lets exploit the public's fears. What worries me is that this is not the only step they will take. This was an easy one for them. I don't think I am being to far-fetched to say that the may start targeting boards like this and other forms of print and electronic media in the near future. They will make the presence of these boards known, and once again start to vilify and attack them. Watch the fear-mongering get worse folks.
Sorry to be a "gloomy Gus" but I think any upside that people see in the demise of the CL erotic section, will be soon overshadowed by the fact that we in this world, (Providers, clients etc) are at war with the Government and the "morality-police", and that this is just the first very public shot. They won a victory folks, we didn't.
