There was a post some time ago from a provider I think who wanted to set up a board for providers to exchange info... She said TER agreed, but just needed to know if there was an interest...

Then I never heard about it again...

But I sincerelly think such violent events as those we have seen over the past few months could be rendered much more difficult to commit if we exchanged more readilly information on bad customers.

In Montreal, there is an Association for sex trade workers who publishes a list of bad clients (non-payers, violents, drunk...) and they post it on their website and distribute prints of it...
