Is it allowed to post articles from another website even if there's a link to the original article? I recently posted an article from another website and it was removed by the mods. I may have forgotten to post the link .
It depends on the context... like if you are quoting a PART of an article or something, yeah... the best thing to do is to put it within the quote BBCode tag and reference the original source with a link. If you are just copy/pasting something, and that's your post... probably a very good chance it will be considered plagiarism and deleted accordingly.
