Though the artist themself marked this as General on FA, I did indeed spend an inordinate amount of time staring at that thar plumpy dumpy, examining every penstroke for the slightest trace of genitalia. Having found none, I decided to leave this post unmarked, racy though the art undoubtedly is.

Part of me agrees with your assessment, and wonders whether the line on questionable content is indeed stricter on Pawb than FA or E621.

The other half of me views asserts that such a shamelessly uncovered hind is not out of question for general-audiences content (e.g. cartoons), views such nudity-dissonance to be an unavoidable part of the Anthro-version experience and its accompanying jokes ("chicken breasts" is another obvious one of the same vein), and fully insists that the general public needs to see dat ass for their Furry exposure therapy.

Truly, I am torn.
