I think they're a way to show appreciation or something (If someone makes it for you)

I have two streams dedicated to me now, and yet I have no idea what to do with them and I have no interest in managing them.
I'm sorry to those who made the streams as a gift to me, but I just don't want them. It seems like a waste. I would rather post in a more popular stream or an already existing stream that has a specific use or theme.
