>>1548550Gelbooru has four rating levels: general, sensitive, questionable, explicit. You can filter results using rating:[level]. You can also exclude a rating by putting a - in front.
>>1548553Compared to gelbooru,
rule34.xxx has a laxer standard of minimum quality, a larger proportion of explicit images, and more western images. You're less likely to find high quality safe for work fan art there, unless you count questionably safe for work art drawn by a porn artist.
>>1548577Before they started blocking everything they seemed to have a lot of obscure stuff. Mostly porn, however. I don't think you would find a lot of high quality safe for work fan art there that you couldn't find anywhere else.
>>1548578I think the deletion of non-anime style art was more common in the past and less common nowadays. Still, the site still mostly only gets anime-style art uploaded to it.
