Hello, I thought of something and just thought to get a quick confirmation/direction: Smokey doesn't watch spam comments, and that's because:
1. (primarily) many spam postings are by one-time 1-rep posters who don't even have the necessary rep to spam comment
2. spam posts have more visibility than spam comments, so getting the former deleted should be higher priority
3. more comments are posted everyday than posts are, and scanning comments as well would exhaust the daily API quota very quickly
