I'm having the opposite problem at the moment - lots of people know that Cesy is Jenny S-T, including people at work and relatives and random RL friends. There are some things I'd like to look at online that I don't really want linked where those people could find it easily. But setting up another identity from scratch is hard work, and then I have to go and tell all the people who I don't mind knowing about the link, so they don't get scared by the sockpuppeting.
