I don't know why this thread is up again after it was created on January 30, 2018. But it is okay in order to be one of the lessons for all members right here. Moreover, now there is a merit system that need to pay attention in order to make the post quality more improved.
As for the rules, hd49728, A.H.Rassel, and other members have clearly stated this.
And after opening the link of the OP, I understand why many posts are deleted. Many of them are shit posts, very short posts, off-topic, similar repeatdly posts.
Moreover, many posts are plagiarized, no enclosing the source link, and also no paraphrasing the sentences from the original articles.
As we can see here as one of the plagiarism done by the OP and most of them are the same.
This can be a lesson for us, moreover a reminder for me in order to pay attention to the quality of the posts and make a good contribution to this forum. No need to worry or feel fear of this all, Just try our best and effort to be a better member of this forum. many members here will help each other.
