To me, that sounds too good to be true so I would recommend you to do things manually.
Here's how you do effective blog commenting for traffic (not for backlinks). Go to Google and search for a blog post that has something like "10/20/50 etc best blogs in niche/keyword..." then within that list of blogs, look for blogs that are frequently updated.
Put them in an rss reader, the aim here is to always be the first person to comment when there's a new update. Old blog posts don't bring traffic, even if they do it's just a few visitors once in a while.
Make sure you comment on blogs that get a lot of social shares, that proves the blog is getting tons of visitors. Don't waste your time and energy on dead blogs that get crappy traffic.
Same process applies to forums, that is why you find that in a forum, the thread that has 5+ posts whenever someone creates a new post, they'll say the same thing that has already been mentioned in the previous posts. Why? They didn't read the other posts, they just read the first 2 or 3 then skimmed on the other ones or didn't even bother checking them.
So you always want to be the first one. Then after you've built your reputation on those blogs and forums, you won't need to rush to be the first one, instead people will be waiting to hear what you have to say.
Traffic that comes from a blog comment or forum thread converts really easy, and always comment on things that are related to what you're promoting to increase conversions.
What I see with these affiliate software is that you find random blog posts and forum threads and add valuable comments but that's not effective. So I advise you to do things manually and hope you'll find my strategy useful.
