I think that the experience of mail operators already tells us everything that we need to know. Short summary: - automatic unlimited creation of accounts is like open relays, very bad - automatic but somehow supervised creation of accounts is like freemails: it can work but it is tricky to get right, even with large resources. And at the very least it needs content-based spam filters. - otherwise, having a real customer relationship with your users helps a lot
