>>33222139 (OP)This site gathers various reverse image search (RIS) sites together: https://dnschecker.org/reverse-image-search.php
I don't know of one that is specifically "uncensored" but if you take a one-two step approach you can find what you want:
1. Do an initial RIS on a face. You get hundreds of hits, most of them false positives.
2. Use your human pattern recognition to pick out the person from the search results. That might give you a name or pseudonym.
3. Do a conventional search on the name. Voila, they have a page, site, Instagram, etc.
