Not that I was told, but it's possible that it had to do with my inclusion of Sub-Q games. It was a while before I realised I was breaching something by doing that.
Of course, for some people it's easier to report and have the whole thing taken down than to let me know so that I'd just remove them. A couple of authors specifically asked that I not list their games, and one of them even said not to include any of his future games. I was respecting their wishes up until someone brought out the sledgehammer.
