Slightly wrong section, this thread should probably be in "Meta" or "Beginners & Help"

Posting a link to an article is fine as long as you add a bit of context to it, eg. what aspect specifically you are wondering about. If you just throw in a link without any additional thoughts it comes off as rather spammy.

Just don't copy / paste articles or content without referencing the source, otherwise you'll get banned for plagiarism.
