Yesterday I received a message on Facebook from someone claiming to be from the FAA. Looking at his profile it seems legit and he actually wants me to call him at his office. He says my videos concern him and there is an allegation of me flying commercially which I have not done. He wants my name and my FAA registration number and to discuss this. I don't mind discussing this with him but I do not feel comfortable just giving him my information especially when I have not done anything wrong. I have no idea what could be concerning in my videos either. Should I call the guy or does this sound like something I should avoid? It seems like a strange way for the FAA to conduct business in my opinion. But I guess he doesn't know who I am so this is the only way they can contact me.
