I agree that it's a shame some books have to suffer ratings that clearly are invalid. However I can't think of a way to prevent it, and I didn't see any ideas in the thread either (I did skim though).

I hope you'll appreciate that if we just start deleting ratings whenever we feel like it, that we've gone down a censorship road that doesn't take us to a good place.

The words of wisdom for today:
Do not read anything that sucks!

Many people have been protesting against what they describe as censorship on Goodreads. I disgree. In fact, I would like to say that I welcome the efforts that Goodreads management is making to improve the deplorably low quality of reviewing on this site.

Please, though, just give me clearer guidelines. I want to know how to use my writing to optimize Amazon sales, especially those of sensitive self-published authors. This is a matter of vital importance to me, and outweighs any possible considerations of making my reviews interesting, truthful, creative or entertaining.

manuscripts don't burn" - "(рукописи не горят)

If there had been a censorship of the press in Rome we should have had today neither Horace nor Juvenal, nor the philosophical writings of Cicero.

Every burned book enlightens the world.
