One other thing you might want to check out Issue #176 of the hard fork that is coming out tonight. By tomorrow posting more than 4 articles in a 24 hour period (or 6 if you space them out perfectly) is going to penalize you on earnings.
You have so many today you may simply be some bot scraping other sites.
EDIT: I went ahead and removed my up vote for this. I don't appreciate the scraping and no response and basically flooding the site with posts from the same person. It makes it more difficult to curate.
Yep...it seems to be that way.
