Does anyone know any other "booru" sites where it is possible to upload hot pictures that are not related to porn?
Dont tell me gelbooru because that site is exclusively made for japanese culture.
:D

danbooru, safebooru

Depends on what "hot pictures" you plan to upload.

Danbooru and Safebooru (and many others) are anime/manga only.
www.donmai.us/
www.safebooru.org/

E621 and Furrybooru cover furries.
e621.net/
furry.booru.org/

Realbooru has photos and real content.
rb.booru.org/

For safe western content... Non-Anime/Furry is the only one I can think of that isn't restricted to a single franchise, but I think that one's dead...
naf.booru.org/

You can search booru.org/top for other sites.
