This is truth. Adding more hay to the stack makes it all the more difficult to find the needle.
Also, what is the worst that could happen if someone finds out it's you? Unless you've posted incriminating evidence that could be used in a case against you or someone wants to hunt you down and kill you, there isn't much to worry about.
