how to block someone on facebook without them knowing?

Don't do things your ashamed of. If you're hiding things from your mom obviously you know you're doing something wrong.

They will know, you can't hide that you block them.

If you block them, they will not be able to see you on facebook at all.

theres no way even if you block her if she looks you up with another account she will know you did it and if you wanna keep it a secret thats means u got something to hide

Honestly, think it over. You want to hide things from your family, but let people on the web see and propagate those images. You really need to join the "rational thinking" club.
