Submitting Author RSS Feeds for Backlinks?

Some RSS Aggregators provide do-follow backlinks as soon as a RSS adds a post. This would be great for easily ranking articles/posts in extremely weak niches.

Is there any software or website that submits RSS Feeds for aggregation and backlinks?

I'm not looking for pinging, I'm looking for building backlinks on automatic.

I always write my articles under a brand new article site member/author and then I take the author rss and submit it through some paid rss submission services that are a part of one of the company's I already use. Gets good easy backlinks.
