It seems if you get three upvotes on a Reddit post/link, backlinks count!
Wow. First off here is some information about the difference between nofollow and dofollow links for SEO. We want dofollow links for SEO. These are the backlinks that the Google search algorithm uses to increase rankings and start flooding traffic to a website!
Here is the Quora question Does a backlink from Reddit count positively toward a site's SEO?:

Yes, if it's a genuine one that gets upvotes. Quote from this article How Reddit Backlinks Affect SEO
"Using the Reddit upvotes algorithm Reddit assigns all newly submitted links automatically as nofollow links, but once a rating of positive three votes or more is achieved the link becomes dofollow and counts toward your search engine rankings."
Note that this is from a service that sells Reddit upvotes and there point of view might be biaised. But I can confirm from my own experience; I even already got a dofollow link with 2 upvotes (not three as mentionned in the article). I suppose that Reddit's algorithm is more evolved than just counting upvotes and also takes into account click-throughs.
