Tin Man - I don’t think they’re getting smarter so much as tineye has just started sucking. Other reverse image searches like Google and Yandex consistently get hits for me. Tineye gets a hit once in a blue moon.
https://www.duplichecker.com/reverse-image-search.php Is what I use. It has a few million ads to ignore, but basically you just need to find and hit the Upload and Search Similar Image buttons. It will run your image through 6-7 different search engines (including Google, yandex, and tineye.) You then just click on the ones you want to see the results of. It’s gotten to the point where I just ignore everything outside of google and yandex. Fair warning for anyone sensitive to non-English sites - you will see some results in Russian from yandex. It also happens to be the one that searches through Instagram making it the best image search tool for finding scams in my opinion.
