Currently, we have a non-public staff area, and have kept a series of threads going. The staff usually discusses a bad post and/or member, with a link to the offending post, and in a separate section, we keep a thread running with the member's name as the thread title, and a record of our actions (and associated staff threads) beneath.
I did notice that in the Notes field, I can paste in a URL and it is clickable. But it is something that in the heat of the moment, a staffer may forget to do. (On a forum with 1200+ online, sometimes things are happening very rapidly as a thread spirals out of control.)
Do we need to see the offending content? Not today, as it will be fresh in someone's memory. But a few months down the road, we may see a reason of "inappropriate content" and need to know exactly what it was that they posted so we can deal more appropriately with a current violation.
