are they? we kind of tend to smash down comments that are even slightly off topic or non-contributory. they might sneak in on the less popular submissions, but i kind of feel like it won't get by any more of a problem than it already is. if comments were more a effective way to spam, they'd already be a problem. alternatives: disallow links in comments until a certain karma/age. disallow both comments and submissions (ha) until you've voted on enough statistically different things. make it a game by creating a new metric that people can be measured on based on the number of spammers they've sought out and identified via flagging, and create a new top list for it.
