Found a backlink on somebody elses Tier1 web2.0

When checking my backlink profile I came around something strange.

Somebody had a link to my site in one of his post. Turns out this guy scrapes reddit, takes title and text of new submissions and makes blogposts out of them on his tier1 web2.0s.

Any idea what tool he uses, to scrape and publish as post? (all automated, scrape and post)

Is this risky? i guess reddit doesn't get indexed before he indexes his pages.. so it would be "his" unique content. And I guess it all hapens automatically.

Any of you do similiar stuff to keep posting fresh content on your pbn or web2.0s? Any tool i could use (i have most tools)

Its most likely a private bot he made or had made.

Reddit also exposes its data through APIs.

I don't have experience on that though.

Probably just has a RSS feed reposter, can subscribe to any sub by http://www.reddit.com/r/SUBREDDIT/.rss
