Thanks for explaining the ban - I messaged you (I suppose) on Reddit asking why, but never received an explanation. I would have imagined a screenplay like this would be of interest to the community, and I couldn't really figure out what rule I had broken, but apologies for breaking the rules nonetheless.
I did in fact announce my (freely available) CG book [0] on Reddit, where it was very well received - 1300 upvotes in gamedev [1], 2500 in programming [2], tons of awards. Turns out Redditors respond positively to original quality content shared for free :)
WSB is not, and has never been, the place to promote your art, especially when you're explicitly trying to raise awareness so you can sell it.
OP did the same thing with a gamedev book a year prior.
Easy ban.
