What do you mean by the expression pack that has been removed from the net?

The expression pack that was removed from the net means that it was hurt.

Sad, heartbroken, want to quit the net.

Quitting the network refers to quitting the network, but usually it does not mean quitting the network completely, but only temporarily. The emoticon package that has been withdrawn from the net also means that you have to temporarily withdraw from the net if you are injured.
