Azrael, methinks it's borderline.
We have two distinct definitions for spam here:
1. Making a topic that exists only to advertise something. (whether it's your website, your birthday, etc)
On the one hand, yes, Plixik seems to have registered a forum account for the sole purpose of mentioning his shield for the Dark Souls contest.
On the other hand, if ever there were a forum that existed almost entirely for promoting your own fanmade sh*t, "Brush and Quill" would be that place.
Eusis will decide, but for my part, I think it's a nicely-designed shield. Which reminds me, we should make our graphics designed Mr. Salbato submit the official RPGFan logo as a shield. :P
