Except chadz, we are all using pseudonyms. Revealing pseudonyms is by definition not infringing privacy.
You could reveal the names of their characters, we will still never know who were the guys behind.
I would disagree on that point.
Some of you I know from your Player name.
Some of you I know from your player name and that you also use it in other games.
Some of you I know from Steam (vast network).
Some of you I know well enough to know your FB and or other personal details...
