Get of my back AC

I have published around 20 articles in the past week. Three of them were crappy, i knew it, and submitted them for performance pay. They the 10,11, and 12 articles I had ever submitted. Today I get a notice that two of them need to be deleted because they are below publication standards.

Why is AC looking at my performance only articles? I have already submitted three articles, why are they reviewing them? Any had a similar experience?

Probably due to many people spamming lousy quality articles on a mass. Could be poor grammar and spelling.

The are simply trying to prevent massive spam that some people tend to post on AC. Usually they do it only when the article quality is really low, like with lots of spelling errors or serious incohesion of the text, but they tend to overreact sometimes. Just try to keep the quality of your submitted articles above a certain level of standards and everything will be fine.
