5050 is a special link shortener. It takes two links and creates one out of them, with a random chance of which inputted link you will get. For example, going to http://5050.degstu.com/v.php?l=rvpzoegslti6qqw will either give you a dog, or a cat. This is used mainly by the subreddit, /r/fiftyfifty. This was made for the moderators of the subreddit. Because of this, its future development is entirely dependent on what the moderators want. Features may come and go based on what they want. Don’t complain about that. You can visit the generator here.
