Ah, but you see, by
copying text out of a
source that has already been
approved by various means, it's more likely to be
good/
useful, and more likely to be accepted by other
noders and
voted up by people who
give a care about those sorts of things.
By writing your own stuff, you open yourself up, make yourself vulnerable, for people to express their disapproval by downvoting, and heading down the road to feeling useless and depressed and suicidal.
People do have the best of intentions when they do such a thing. (or at least usually) That doesn't make it right, doesn't change the fact that it's not wanted. Just a change of perspective here...
