Nothing is private on the internet and deleting a message does not make it gone.. Some things are harder to see though for the general public.
For the most part I dont think we need to worry much in the discussion of the science and the treatments that truly have helped so many. As Redd says keeping it real
I was privy to a great example of internet sleuthing in a public school system a few weeks ago as they traced a message thought to originate far away on some pacific islands, around the world and back to one of 32 computers in a firewalled and protected high school computer lab at x time of day along with the logon user name who had deleted both his account, the cookies and the message in Minnesota.
Imagine what can be seen if someone really wants to see.
