They will tell you lies about what will happen in terms of marketing. They will sell your details to every book-related scammer on Earth who will be contacting you about idiot TV appearances over a decade later. And they will print 50 copies of your book for around $5000 USD and call you a few times regarding a marketing campaign that doesn't exist, just like all the other vanity publishing scammers. Still being contacted daily by mad people from all over the world about my long dead brother's book which makes it very difficult to try and forget about what happened.
