We're quite aware of the rules for N4G:
"Submitting your stories to N4G can be a great way to promote your site and to gain new readers."
Since it's rather easy to check a poster's submission history and it's perfectly fine to self-promote, there's no reason to hide behind an alternative username.
Thanks for the concern, though. :)
Since we're accounting for North America exclusives, it's only natural to find that majority of the titles are from SCEA.
