lol, I think the same phrases appear about a hundred
times on google without
a mention. the problem that we have is that plagerism only seems real if it
can be googled (or in our case if we know the text quoted). Text from books
could go unnoticed for months unless an editor smells a rat. Four sentences
from a Wikipedia article (albeit follow through sentences) have shook enough
people to respond, how about if four verbatum sentences from a book were
posted in wikipedia? would we be shocked at the copyvio?
Plagiarism is real and (as far as I'm concerned, and I would imagine
pretty much everyone else) seems real regardless of the source, it's
simply very difficult to spot when it's from an unfamiliar offline
source. If we found out about four sentences in a Wikipedia article
copied from a book we would immediately remove them, we're just quite
unlikely to ever find out, which is unfortunate, but unavoidable.
