ITsonic, we are pretty tolerant here at THG regarding links to other sites.
Copying and pasting an entire article (3 times) from another site is however, a bit over the top.
The site Editor in chief's (Chris and Tuan) are likely to take a dim view to you posting articles from another site without prior permission from the author, or giving their own consent.
Whilst the articles are interesting, a simple link (so we can look for ourselves) and some of your own commentary (which is sadly lacking) would be more appropriate.
I hope you understand.
