A feature to exclude specific contributors from search results

When I search for images and use the “exclude AI-generated images” filter, there are still many clearly AI-generated images showing up, which is frustrating. If contributor tagging cannot be controlled because it may be done maliciously, then please allow users to exclude those results for their own protection. I would like to be able to exclude specific contributors from the search results. It would also be useful to set multiple contributors, and I would appreciate it if those settings could be saved and kept once registered. Thank you.
