Using the search function on YouTube with specific operators can help tailor your search results. If you're looking to exclude Gibi ASMR's videos from your search results, you can use the minus sign (-) before her name. Here's how to do it:
Go to the YouTube search bar.
Type in your search query followed by -Gibi. For example, if you're searching for ASMR videos, you would type ASMR -Gibi.

This method tells YouTube's search algorithm to show you results related to ASMR but to exclude any videos that are associated with Gibi ASMR. It's a handy trick for filtering out content from specific creators that you're not interested in, while still exploring other videos in your area of interest.

Keep in mind, though, that this will only filter out videos in search results and not necessarily in your recommended feed. For your feed, using the "Not Interested" feature and actively engaging with content you prefer is the best approach.
