What is secret mode (secret comments)?
Putting a check in the option Enable secret mode on the video player
allows you to comment with an encrypted account ID.
Secret comments from other users can be displayed by putting a check in
the Show secret comments from the player's filter settings tab.
Account ID encryption is changed once a week for reasons of security.
If you have added any users using secret mode to your block list, then
please be sure to add them again.
