Because Raptr is sinking man. It's been month since it can't login to Steam chat for example, or stopped supporting console accounts, but the stuff is kept anyway. They don't have the time or the resources to remove them and give the program's interface a much needed refresh. Just look at the rewards: do they seem like a reward system to you?
40% of Raptr is like necrotic tissue and needs to be removed. And the 60% staying needs fixing or updating.
