When I search for just about anything there's a few, ok a ton of, porn listings that come up.

I can understand if one of the words I searched coresponded with a word in the porn listing but most DO NOT.

I search my last name, results = a ton of stuff that's porn and is no way has my name in it.

I search for anime/manga/anime songs etc... and mostly the results are porn that matches none of the keywords I put in.

Yes, I know about filtering, I was just wondering why my searches were returning these results when they don't match any of the words I searched for.
