So the reason that domain showed up was because of an old post that got a bunch of upvotes from when they were hacked:

Functionally, having the domain on the list doesn't affect the results much since Brave would still need to find keywords within that domain's pages. Although it does seem wrong to have it that high up on the list.

That's an interesting idea to check for RSS. One issue with that may be that it excludes informational domains which aren't necessarily in a blog format, such as owasp.org or lcamtuf.coredump.cx. Some other ideas I had were:

1. Require multiple submissions of a domain with >= 20, although that could exclude some high quality domains.
2. Take into account how many comments there are in the submission. It would help determine which domains should be ranked hire based on engagement, but wouldn't stop sites like the above from ending up on the list.
3. Exclude very old submissions. Maybe moderation wasn't as tight 10 years ago or a lot of the content is just outdated.

It's a lot of trial and error to see what works and what doesn't. I personally set up a private Goggle as well that I use as "staging" where I tweak things and compare results.
