I do the the opposite with user names. I randomize all the accounts on every site I go so there would be no link between those (except the fact that all of them look random), But I don't hide anything and always assume that even the passwords to these accounts are public. As a matter of fact I literally have them all in a file as plain text username/password. So, it keeps me from doing anything I would not like anyone to see me doing, but when somebody enters my name in a search bar they don't automatically get to see everything I like to do on my free time.
