What is consideration? gives the test: Don't consider a node unless you feel strongly that something specific should be done. That seems to be inherently somewhat subjective and capricious.
What makes one brief note with a link (say a pointer to some news) okay, while another rubs us the wrong way? Could it be we find shameless plugs deplorable? Could it be we dislike deliberate attempts to make us click and play fetch? Nay, methinks the "spam" designation was not far off the mark!
Furthermore, the repost does not strike me as a quality node either. Section of code that does not run. Link to identical content, offsite. Do you want me to click some external links, do you?
There is no substitute for editing. Not editing your nodes is disrespectful to your peers. Anybody interested in testing the code will need to fix it first. Not only are you delegating secretarial duties, you have everyone duplicate the effort.
What is spam?
