They automated mirroring posts from Reddit as a way to add content here (don't provide links to original posts either or make it clear that the content is mirrored). They don't really vet what they post either. Something thing they reposted from reddit was a person asking for help picking out PC parts for a gift, a post which the original poster would never see, and people here would just be wasting their time replying to a bot post instead of helping the OP. They've also repost the same article to the same community a couple hours later.
