It's okay for Reddit to make money off of stolen content but the moment anyone else submits a link that has a 'tiny' ad somewhere on the page (even if the content is highly relevant) to a subreddit, they drop the BAN hammer and create new subreddit rules to stop those 'horrible' spammers.
Google, Youtube, FB, Reddit, Tumblr ... all profit from other people's content yet look down on anyone who wants to also make money.
