People do not like thieves which include plagiarists. These individuals simply copy paste others work and by doing so, they also steal page views and hard earned cents from the original writer. Sadly, an online writer (at least, an honest one) can be a plagiarist without him knowing it.
I have a friend who was a writer at triond.com three years ago. She has already written a hundred articles when she decided to start all over again. She created an account at bukisa.com - another article writing site and began publishing under a new pen name. Over time, she considered transferring her Triond articles at Bukisa. However, to do this, she needed to delete her articles at Triond since she was already using a new name. All went well, until she received an ill comment about one of her content as a duplicate.
