BTW, she has comments turned off on her posts too.
So she tells you to join so she can talk to you, but your odds of getting her attention are actually better in her Twitch chat. I'm surprised she hasn't made tipping her mandatory if you want to send her DMs. She probably doesn't know she can yet.
I guess, in theory, you might get more from a big OF tip might than the equivalent amount of Twitch gifts subs.
