If you try to use Reddit for the sake of site promotion, you're generally doomed to fail. Especially if your Reddit post history consists solely of submissions involving one website.
If I browse any of the new queues for Reddit, I downvote anything submitted by an account with almost no post or comment history save for submitting links to the same site. If a Redditor has multiple submissions for a site, and doesn't seem interesting in otherwise participating in the community, I ask the admins to blacklist their domain.
Now if you owned a successful automotive blog, made comments in various threads, and submitted the occasional link to your site in an auto subreddit, that could be successful. The only exception is when a business (GoPro is notorious) uses shill accounts to submit videos for viral marketing purposes.
