I am getting a lot of bad requests from a crawler at a specific IP Address non-stop. I added the IP to the blocked list and cleared the cache, but I still see more requests in the dblog coming in from the IP:
HTTP response: Bad Request. URL: https://valid.url.example.com/api/123456>; rel="canonical",<https:.json.
Why can they still send requests? Is there a way to prevent these?
