The thing about the public instances, is now you often have to go through a lot of them to verify they work properly. SearXNG needs better quality control.

Often have to go through the preferences to deselect search engines that don't work (often because of the instance being blocked) or select those that do work, because of reliability problems. Which engines are working, can be different for each public instance, so that even saving a preference hash doesn't always work.

Would be great if SearXNG did automatic adjustment of presented search engines (or offered the option) based on reliability.
