Max,At this juncture, I would advise you to get a lawyer! Have you checked to see if there are any non-profit organizations in your area that could help refer you to an attorney? You are NOT obligated in any way to provide ANYTHING to these people!! If they have a complaint against the Mudcat, then they must provide evidence of their complaint. Don't let them talk you into doing their dirty work for them!
I hope that you are keeping WRITTEN records of your conversations with these people, as your records could be used as evidence of your actions, in good faith, to find a reasonable way of dealing with them (if, God forbid, this goes to court).
The only way you can be made to provide ANY information to this attorney is if it is subpoenaed in a lawsuit. Do NOT let this person bluff you or bully you into ANYTHING!
Again, I would strongly advise you to get an attorney ASAP. Contact your state's Bar Asssociation for help -- their number should be available by calling information; or contact a local non-profit assistance organization. Until you get some good legal advice, I would suggest that you do not communicate further with these folks.
