First time logging in for almost 9 years. I had no idea people still even looked at this account!
The short answer is back in '05-'06 I had a couple admins that kept deleting some of my submissions, giving me only a link to the ToS as their reason and refusing to clarify. To my knowledge I never violated the ToS, but I couldn't get answers, and after a while I moved to other sites.
Sorry for not leaving a reason; I've never been much a fan of the "Leaving foreverz!!1" journals and prefer to leave quietly with as little fanfare as possible.
