There's an anon who deliberately tries to chase artists away from threads like these by being extremely negative and unreasonable, so keep an eye out for that. Some sort of weird grudge from the dedicated draw thread I think. Remember, you can hide posts by clicking the arrow next to the post number.
Also, as you've noticed, janitors can be a little trigger happy in here because technically these characters might be considered 'furry'. You won't usually get banned, but I think it's happened. Better to just use imgur like you did earlier if anything is even slightly risque. I'll put it up on the booru from there.
Hope you enjoy your stay regardless of these minor inconveniences.
