Tweet

This morning when i try to log in my Helium account, i can't log in, (i have not use internet for 4 days because of the festival), then i check my email box, there is a notification as following: We’re writing to inform you that we have removed your article written to the title, "How to help your child handle a friendship breakup." Your article is inserted below. Your article was deleted because it falls below Helium’s minimum word count or for other editorial quality issues. Your account at Helium will be closed. Helium has increased the minimum word count to 400 words, based on research that maximizes writer exposure and earnings. We recommend article lengths between 400 and 1,500 words. Your article may have been submitted before this new word count minimum. In fact, My article has been there for about two weeks, and as you can see, it also said, it set a new standard about the word count, well, if it falls under the new standard, it should be deleted, but what i could not understand is why it deleted my account without any reason. I have not violate any guidelines. And what about my earnings? I once feel this site is a fantastic website, but i really could not understand why they do this. They close the accounts of all those who once wrote an article with the word count under its standard(NEW STANDARD)?
