I find this very hard to believe. If so it makes the PFA and Clarke Carlisle look even more stupid. So, you're saying, they hire a comedian with a known track record who's stand up routine is based on using the word ****** and then ask him not to use it. Why not just go elsewhere in the first...
Very much this. They hire a known comedian with a known style and complain when he does what everyone knows him for. It's a bit like moaning that your dog barks. The PFA goofed up, no big deal, move on.
