Yes we have but I would suggest AT isn't in the same league as those operators.
As much as I don't like the man he is quite an intelligent operator who knows what he can and can't do and how to cover his arse.
It wouldn't be fair to give any wannabie the idea that it will be likely possible to recover any money from the situation.
If they with the knowledge that its unlikely still want to chase him for annoyance, !!!!s and giggles fair enough. But if they are chucking good money after bad its unfair not to warn them what they are getting into and the likelihood of success.
