I have just come across articlebase.com and i have seen that they are providing free articles to publish( correct me if m wrong), i own my personal site and i need some articles so can i just copy articles from this site (the free ones) and publish in my site????? without any problem???
Ask them, read the copyright terms of use. However if that's what there advertising them as wheres the problem?
Read their TOS. Off topic but copying and pasting an article onto your site is not going to do you any good...do some research on duplicate content.
Yeah lots of articles sites let you copy the articles to your site, if you keep the "about the author" links. But this won't help at all, Google will slap you for dupe content and you'll never see organic visitors.
