The fact that reddit enabled hiding your posts is crazy to me. In a time where knowing who's engaging in a community is more important than ever (am I talking to a bot or a troll?) reddit removes even more options to validate.
The better fix would be to make the support for multiple accounts in the reddit app not so incredibly-shitty, where you're basically logging out and logging back in. Instead, just tell it "posts to this sub use this account, posts to that sub use that account", etc.
