That could backfire on you...you might get a reputation for "blabbing secrets" when they trusted you to not out them. Sure, it probably won't affect those who genuinely like you...but managers (and other higher-ups) like to know they can trust a worker to not "out" people, ideas, the company, etc.
No one will tell you they don't trust you...but you may feel the sudden chill in the air.
Take the high road, and let the embarrassed ones go their own way.
