How do i block another member of cafe mom?

.what's the point of still communicating thru q and answer then?

Imagine what would happen if you couldn't see what people said to/about you, but everyone else could - you answer a question or group post, person you don't like and calls you (insert every word that deeply offends you here) and lies, saying you've done X,Y,Z horrible thing in your life. You can't see it, everyone else starts responding to it. Since you don't defend yourself, other people start believing it. Or, conversely, people start quoting it when they respond to it, so you see it anyway.

It's why most message boards with a block function have it built in to instantly unblock any individual answer, might as well not have a block at all.
