Why comment spam is more evil on small blogs: a completely biased opinion

Being slightly less than serious for a moment, I've decided on another reason comment spam is evil (aside from the whole unsolicited junk, ruining content of an otherwise good site, making people sift through often offensive nonsense reasons). On a small blog (such as this one), any comments are basically mini high-points for the author. When I check my mail and find that there's a comment awaiting moderation, it's a great feeling to think that some of the nonsense I write has actually caused someone to write a reply - it doesn't matter whether it's positive or not (though that's nicer), it's just nice to know that it's being read by someone and that they'd like to continue the discussion with you. Now we come to comment spam. When I click on the email telling me I have a new comment awaiting moderation only to find that it's a list of links to casinos, viagra and other drugs I've never heard of (probably more of the same ilk I imagine), it's quite more than a little irritating. It's a classic quick high-to-low scenario and it's just not fair to play with the emotions of we poor unpopular bloggers. I'll be honest, I'm blowing this out of proportion slightly, especially as I don't even get much comment spam, but I did just get one a moment ago and it I had nothing better to blog about :P
