A whole lot of publishing houses look at works posted on blogs as "previously published". Now, let us say I put something on my blog and it is around for some months (or an year or two). One (not-so) fine (a) day I decide to get stuff published. I take down the (let us say) story off from my blog, wait for a few months (hoping that the cached versions will be wiped out) and then submit it to a publishing group.
My question is: does it still count as "previously published"? Ethically, I would say yes but what would be the legal status on it? If no one can see it, does it still remain published?
P.S: I understand that Writers is not a legal advisory group but as writers, what are your opinions from experience (in case a straight forward answer is not possible)?
