If I open an entry, the user is visible and I can just select it hit Control+C and paste it anywhere, there is no indication in the logs for that.
You have a log that you have opened the entry, isn't? Even though we find a way to catch the ctrl+c, as soon as you have seen it, you can type it or do a print screen

I understand, I think that you need o make this as hard as you can on the user and force him to use the PVM features for coping the username.
Maybe don't display it as a text window...
