as an administrator I would like to understand how to obscure posts without necessarily deleting them. I tried to use the "hide" function but it seems to hide it only from that user and not at all.
Hi Giacomo,
The only way to hide a post from users is by changing the privacy.
You can try changing the privacy to 'only me' so that only site admin and the stream item creator can see it: http://take.ms/02jpU
