I got banned from using FB's ad service a long time ago. I was linking to sales pages for my own books for a few years.<p>One day I got an email saying "You are no longer allowed to use this and the decision is final. You may not contest it" or something like that. I responded asking for more information and they wouldn't give me any.<p>So, here I am, still trying to find a viable alternative. My novels and poetry books don't really sell since then, which is mostly my fault for being lazy, but I was getting rid of a few here and there before.<p>Sucked that they had such horrible customer service tho.
