I'm seeing a lot of 404 errors with slugs related to cryptocurrency (not my website's industry at all). We've never created pages remotely similar, but I see a lot of 404 errors with keywords like "bitcoin" and "litecoin". Any recommendations on what to do about this? Another keyword is "yelz".
It usually presents like .../yelz/-ripper-vs-steller/ or .../bitcoin-vs-litecoin/. I don't really even have the time to fix all the legitimate 404 errors, let alone these mysterious requests. Any advice is appreciated.
