@Forestofglory there was someone i wanted to follow who posts followers-only.
I think I sent a follow request ages ago, & they must have rejected it. So I sent one again, not being sure if I'd done so already, or maybe there was a glitch.
After that, I noticed that they had written on their profile that they weren't accepting follow requests from people they didn't already know.
So I felt a little bad about that, in case I'd sent a follow request without noticing their statement about it.
