There seems to be a strong emphasis in search results on domain name match, similar to Google several years back. e.g., search "dog training" and examine the results - there's a much higher mix of spammier content mixed in with helpful content than you'll see in the other big name search engines' results.

Anyway, keep cracking at it; I'm sure you'll get it sharper as you go.

There is, but the bonus goes down as we get deep indexing. So if you check back in a minute most the time the spam will have moved down.
