Really? It does? I’m following her, but if her Tumblr requires a password now, then it was probably after I followed her. I think it’s to prevent all the asshole Motionless In White “fans” from harassing her. I followed her when I first made this blog a few months ago. I would recommend tweeting her, but she’s kind of stopped using her Twitter. She’s following me on this blog, so hopefully if she see’s this, she might be able to help you out.
Edit: I took a look at her blog from another side blog of mine and tried to follow her, and it seems that you’re able to follow her without requiring a password! Are you sure you have the right URL? There are people on here who are pretending to be her. She changed her URL! Someone might have claimed her old URL, or she may be hoarding it. Whatever the case, you’ve got the wrong blog.
