BAD BAD reviewer behavior and BAD BAD ethics

There is an editor who is putting on a reviewer hat in order to list out all the errors they can dig and find. This editor then points out a short list of errors and says– I'd never buy this book because of the errors. Then you are threatened with — this is an EXACT quote:

This is just a tiny sample of problems in this story. If you really, really want a review on this story, I can do that but you aren't going to like the rip I'll do on the editing that's been done on this story.

Or, I could edit this for you. I charge $5 per page for a project under 100 pages and $3 per page for 101 to 750 pages.

EXTORTION — I will overcharge you to edit this book or 'rip' the book!

Can you say FURIOUS!!!!!
