When you block someone on facebook, does it block them from mutual groups as well?

I bought a horse 2 years off a woman, lo and behold she finds me on facebook a couple months ago (literally a week after I'd sold the horse to someone else) Now she is constantly harassing me about wanting the information to new owners so she can keep track of the animal. Not only have I told her I've lost all that info, I feel it isn't her place to continue to "stalk" new owners, she sold the animal, its no longer her business. Still she continues to ask and harp about getting his name, number, and where he lives/works.

Anyways, I'd like to block her, but it would be pointless because we're part of the same facebook groups. If I post something on a group or comment will she still be able to see it? Cause if she can I know she'll just start asking there as well.

***I know she won't be able to see me or my private page, but if I venture onto "public" group walls, can she see me?
