This has really gotten out of hand lately and I think there should be a more hardline policy on this. Many other large message boards do not condone copying and pasting articles into posts for two reasons:
1) Threads a easier to read when people just post links to articles instead of an unformatted jumble of non-paragraphs and dead links. You can't tell me that anybody actually wants to read that shit.
2) Copying and pasting articles into posts often violates copyright laws. You are distributing someone else's work without their permission, that is illegal. One could argue pasting an article is within Fair Use. However, Fair Use of someone else's text is not a legal protection, it is only defensible position. Now its unlikely anyone would take legal action for such a violation, but its best to be safe in case an extreme example arises.
