2D EFRO 'questionable' content is rare? Out of 55 million pixiv works and around 20k hard scat ones, 10k is questionable EFRO, just farting, taking dumps by themselves and gaman.

What's a little bit scarce is SPEFRO, aka the girl having fun doing it all by herself or masturbating to it without a need for drugs, mind control or anything like that as a catalyst. About 1k of it on nijie, pixiv and hentai foundry altogether.
