Don’t know why blog was turned off

I had a blog about best management articles to read for business executives. It’s been vaporized, and I have no idea what I’ve done wrong. I always link to the article or say if it requires registration. If I quote, I do so briefly and in indents. It was plainly only brief reviews of what I’ve read and am suggesting others read. Somehow I managed to violate TOS — but I haven’t a clue how. Now I don’t even know where/who to ask.
