I don't know, Mom2all. Privacy gets tricky when it comes to comments. And picture tagging. For example:
The same is true with photos. If anyone is tagged, that person and all their friends (even ones you've blocked) will see the photo. And they'll see you linked to a Facebook account if you're tagged in it.
Basically any one can see what another person has commented on. So unless you can control all your friends' settings and behavior, you're likely to show up their feed somewhere.Lucy (14) posts a picture of a grouchy cat. Her friend Suzy (14) comments on it, "LOL that reminds me of my cat Fluffball." Lucy's mom (37) also comments on it: "What a cute kitty!" Lucy's and Suzy's moms are Facebook friends, so Suzy's mom sees that Lucy's mom commented on a post: "What a cute kitty!" So she clicks on it to see for herself, and under the grouchy cat picture she sees all the comments everyone has made on it. Including her daughter's. Even if Suzy is using the fake name "SZ girl" or whatever, the content of the post (she has a cat named Fluffball) and the fact she is a real-life friend of Lucy is enough for Suzy's mom to realize it's her.
The same is true with photos. If anyone is tagged, that person and all their friends (even ones you've blocked) will see the photo. And they'll see you linked to a Facebook account if you're tagged in it.
