How do you block someone on facebook chat?

[Roy]

I think one of my friends has blocked me from facebook chat, although we're still friends on facebook. How do you just block someone on facebook chat? Is there any other reason why they might not appear on chat?

They might have put it offline...

They can go hidden from everyone so no one can see there online , it doesnt mean she bloked you.. but thats still possible

To block someone on facebook chat click "friend lists" a menu appears in the box that says "type a list name" put in whatever you want to call the group. Once its named it will appear in the menu with people to chat with. Click Edit next to the group you just named and you can add people you don't want to talk to or see. You'll notice that there is a green little slide bar. If you move it over so its gray you appear offline to whoever is in that group. To let them view you just move it back to green. They may not appear on chat if they unfriended you, they blocked you, or they changed their chat status to "offline". Hope this helps.

If you go to someone's profile and block them, that might be one way of not be online, also, they have an option to be online or offline; it's at the top right corer of your chat list of online people. Also, they might have made a group and only put you in it, that way, they can appear offline for only you and will be online for everyone else.

You can't. Either you're offline or they are. Facebook chat lacks many of the features normal chat tools have.
