I can't use a search engine without uBlacklist anymore. I've been spoiled. There's just way too many garbage sites I don't want to see. I'd like to use Kagi, but I can't until a uBlacklist-like feature exists.
If you decide to support a uBlacklist-like feature, please consider this scenario:
I block a lot of sites; over 100,000. Some of my search results yield 0 results on the first page. Without a userscript, I have to browse to the second or even third page to see any results. The first few pages are filled with garbage I've filtered out. Loading more results automatically with a userscript works, but I'm consistently flagged as a bot and have to complete captcha after captcha.
If I could import my uBlacklist lists and non-filtered results were nicely compiled on the first page, I'd start using Kagi.
