Can you block a facebook profile?

[Kara]

I wish to block my siblings facebook profile because she spends hours and hours on it and won't let go even if I need to use to computer just for a while,

You can block a facebook profile from contacting you....or viewing your FB info...But you can not block someone from going into their profile or using theirs w/out their password etc.

All I can suggest is you talk to your mom and dad, if you need to use the computer, then you should talk to them to make sure the use of the computer is fair for all your siblings.

Edit:
You can change her PW....but she can reset it...and get it back.

Find her password somehow, and when you are on computer, change her password,
she will never be able to access her account again.....LOL
