A friend of mine, author, whose book was published by DIP Publishing has cancelled her contract with them because of no royalties forth with. So, naturally being sad for her, and having been through this with Trestle Press (grrrr), I did some of my own research. Seems that some people have been receiving invitations from them, just out of the blue (red flag). Goes like this:
"Greetings to you,
My name is Sophia and I represent DIP Publishing House. I would like to discuss a potential publishing opportunity with you. This opportunity is not for Self-Publishing, although our company currently offers those services...
This is an aggressive marketing strategy targeting anyone. If you, yourself, did not seek them firstly I would be a bit leary. To me that is a big red flag. Always, always, research, I say this out of experience.

So any of you that receive such an invite...ignore.
