They twice deleted my account because my regular postings sharing links to my e-book on their site apparently activated their "spam filters". Yeah, that makes sense. But what is much worse is that they never notified me of this or why my account was suddenly gone and I couldn't log in. They never sent an email. I simply had to contact them directly, confused after the fact that I could suddenly not log in. Their first response when I contacted them also clarified none of this eventual truth I found out. They simply said there was no account linked to that email and did not respond to any of my follow-up questions. So now very confused and annoyed, I went to all the effort of re-creating my account since they insisted I'd never signed up in the first place. Then they deleted it. Again. And after I demanded answers, they finally explained the supposed spam filter thing. To summarize, they are the worst book site I have ever used, a complete waste of time, and I recommend that no one use them.
