I've built a D0F0llow checker tool to use with ScrapeBox and other custom tools I have. My question is if you would be interested in buying such a thing. I use it in it's unpolished form but if enough people are interested in having it I will obviously make it nice and smooth. What it does: Finds all d0f0llow links on a page and detects if they are: In sidebar In header In footer In post body (both for forums and blogs) In signature (for forums) Comment author name (for blog comments) Comment text (for blog comments) In a list (common situation for blogrolls or sitewide links) Within text With all that data you can take your huge list of URLs from ScrapeBox and paste it in, then you just filter out anything that doesn't interests you. For example if you want to keep just blogs with d0f0llow comment links, you keep only URLs that have d0f0llow links on the comment author name or within the comment text. Obviously it is not 100% accurate (no scraper is), but it has a pretty high accuracy (I would say over 90%). For default installations of the forum and blog platforms it will be 100% accurate and should work very well with customized installations as well.
