It’s everyone’s business to make engines’ spiders indexed these links and these pages with your backwards links. Spiders like to index everything, but you need to let them do it - you need to create opportunity for this.

Dude, it is better to ask about this experienced black seo guys who working with such type of links.

Spiders index such type of links and pages (differently in different engines), you need to practice in this. So you must make that these pages will get indexed (and look at results in different engines, because some are indexing such pages and some are not). I have different experience with it and I’m still researching in this area.
