Just lurk around a bit, see what gets approved, and adjust accordingly.

I see several problems
A) Game CGs are generally looked down upon
B) Game CGs where you don't even know the artist or even the game are even more looked down upon
C) Game CGs of extreme fetishes like Bestiality are especially looked down on.
So yeah, thats three major problems right there. If you don't have any images to upload other that ones like that, just don't bother.
We really need that "why weren't my images approved" thread that keeps being suggested. (forum #44803 and elsewhere)

Generally I learned a lot by asking what contributes and moderators what they look for when they upload/approve, and looking at what artists/pictures are likely to be approved.
If its a niche, especially bestiality, you have to be very choosy what you upload and really look at something with more mainstream appeal or high-quality art. Avoid things that require a lot of translation with little/poor pictures, and upload a few things at a time from that niche, you should really have no more than half of total uploads at a time, and usually upload 2 out of every 10 pictures from that niche if its unlikely to get approval.
On the other hand, if something requires a lot of translation and you actually DO that translation (or someone else does it for you, I'm not picky), that would substantially increase the chances of the post surviving moderation, as far as I'm concerned. I've certainly seen posts with translated text on them that I've approved (or untranslated text on them that I've translated and then approved) that, if there were no text on them to begin with, I wouldn't give a second glance.
