Now that I have begun to post more regularly to this blog I have seen a surge of comment spam. Sigh.
Sadly it appears to be coming from humans rather than bots. So someone is paying for humans to do this, or has purchased fancy bots.
You know what would be cheaper and actually effective? Would generate site traffic to your website and generate good will? Paid advertising.
You can buy a week's worth of advertising on low traffic blogs from Blogads for as little as $1000. Or you can purchase a sponsored post on Reddit, which will appear on the top of the sub-Reddit you select, prices begin at $20. Or you can purchase some keywords on Google, Yahoo, or any other search engine.
