Bizarre email complaint

[Bat21]

I received this email last night:-

after sharing some pdf files that I was not aware of any copyright being owned by you, I find it a sorry state that you kick off on facebook about it when all I was doing was helping a fellow terrano/maverick owner out of the shit. please feel free to close my account as I will not be paying for the membership again. I would also suggest that if you are going to spit your dummy out that you ensure that people are aware of copyrights. oh and whilst we are on the subject did you get permission from Nissan/ford to reproduce their manuals electronically or otherwise...as I said feel free to remove my details from the site....

I replied telling him that I have no idea what he is referring to, but as yet I have heard nothing back from him

As I have no idea what this chap is rambling on about, could anyone cast any light on it
