Thanks for the feedback. I want to wait a bit to see how things are going before contacting a lawyer as I assume it's not going to be cheap, although I could certainly fix my own name! And indeed I'll also remove the Postgres mention.
Good point about using the service as storage space. I see Evernote doesn't have such a limit but their data is not encrypted so presumably they can prevent abuse by scanning attachments, which I cannot do. So thanks, I'll look into this and maybe put in a storage limit per account.
