I need facebookhelp!?

[Poepa]

Alright, here is the situation. A couple of friends and I have a groupchat on facebook. Someone thought it would be fun to add a random person. The problem is, you cant delete that person. That particular person added like 10 of his friends, so it started a complete chaos. We know we can block them, delete them or delete ourselves from the chat but the problem is: they can see our history. And that is like... A huge deal.

Does anyone know an answer? Thanks.

I never use Chat, but maybe it's more or less like Message.

As your worry regarding the new participant can see the previous conversation, they already did, and have in their end, so it's irrelevant now.

The problem with group chat/message, we cannot expel others; as you said you can block each one of them so they can't involve in the chat anymore. That's so far that you can do.
Sorry.
