Yes, I'm familiar with booru sites. They are imageboard-style websites that allow users to upload and share images, often organized by tags. Some popular booru sites include Danbooru, Safebooru, and Gelbooru. They typically focus on specific themes, such as anime, gaming, or other fandoms, and users can browse images based on various criteria like tags, ratings, and more.
