>>5564959>Reverse image searchRIS in jargon, sometimes.
Yandex, especially if you have an account there provides indeed good service. Russians are not that politically correct in restricting searches regarding content, unless it's about their government business and Putin himself.
SauceNao's main source is usually Pixiv user base. The good bit is they store the pointers although the account would be closed, which gives a shot for further search, sometimes based on a different pic.
However if you make an actual deal with Google on unrestricted content it really will deliver. Corporate level paid services are just another level. Ofc your employer won't be happy about your lunch break habits :DDD
