How do I block someone on facebook that has already blocked me on a mac?

[Magnum Garcia]

Hi guys; I'm not very good with facebook, but I really need to know how to do this; there was this toxic girl stalking my profile, and I told her to quit stalking me, so she blocked me. Oh, I should probably mention that I did the initialchatfriendslist thing from viewing the page source in order to discover that she was stalking me. Anyway, her number keeps coming up on my initialchatfrienslist, so I know she's still able to view my profile, but I can no longer view her page, and when I type her name in to block her, then it will only give me the pages of others using the same name. How do I block this toxic girl? Thank you very much for your help.

She already blocked you. So you can't block her after she has done it. Yes you can block her if she unblocks you. But it depends if she does or not.

initialchatfriendslist doesnt show you who is stalking you

and she cannot view your profile as long as she has you blocked

If she blocked you she can't see your profile and you can't see her.
You cant block her and there's no need to as she can't see you

Keep searching for her, the moment she unblocks you, you can block her.
