The problem is that spamware reports where it has submitted to. If you operate a blog, forum or any site that allows user content you should do your best to remove footprints (ie. powered by wordpress, vbulletin, etc.). This makes it harder for spammers to find you.
Use captcha where you can, but try to use Solve Media or at the very least ReCaptcha. OCR software is unfortunately cracking easy captchas, which are no longer a major hurdle for spammers.
The goal is to reduce the successful submissions that these spammers are getting - even if you don't approve them. Moderating spam comments is no longer good enough - you must take aggressive steps to get the spam under control. If you can successfully hide from spammers, it may allow you enough time to get a handle on disavowing those bad links. If you don't want to take a tough stand to stop spam, like some clients I know of, you will find little time to create content because you are spending a significant amount of time scrutinizing each and every new link that points to your site.
