content: You're going to find a lot of reddit reposts, don't worry about it.  Some people find content on their own and post it here, some repost.  If people upvote they probably haven't seen it on eddit before so just let it be.  If you spend enough time on either site eventually everything will look like a repost to you.  It getting posted on one site or the other doesn't mean that site owns it.  A lot of people here don't go on eddit anymore so they could give 2 shits if it was posted there before.
