@Robert Trusardi I have gotten a lot of constructive criticism so far and it’s been helpful, but I’m done with that phase for my current book The Burned and now I only have negative seeming comments. It’s a bad image when you’re on preorders and are loaded with criticism instead of positive feedback. I recommend that you go through and delete these comments before launching the campaign, they’re good for when you need them, but once you’re satisfied with your product it’s bad for your image. Personally, I’d love some positive comments (I have a few positives, but some seem harsh when out of context)

It’s tricky territory - that’s were the writer should state on their behalf if they are seeking said feedback. Some writers are very protective of their expression.  Perhaps just ask if it’s ok with them if you provide constructive criticism.  No harm in asking. Right? 

IMO it’s quite unethical to leave unsolicited feedback or criticisms. If the writer is requesting  constructive censure - then have at it. Otherwise it’s best to promote the positives. 

Personally I don’t mind a little constructive criticism - but when I leave comments inline I try to make sure I highlight what I like and leave positive comments. If someone has asked in the forum for a more in depth analysis then I’ll dig in a bit deeper.

I’m wondering how people feel about making comments on books in funding mode?  Should they only be positive or is it OK to leave constructive criticism?  Seeing as how these books are in FUNDING mode it almost seems counter ethical to make criticisms when these books are trying to make presales...  I’d like to know what other people think.
