I've not had any spammers try to add me as a friend for along time now, and as a result, I've decided to make most of my entries public again, but if spammers and fake accounts, etc become a problem again, I'll probably change it back. One of the reasons for this is that I never intended it to be friends only anyway and I don't like the idea of closed accounts (ok, so they're essential on sites like facebook, which aren't really anonymous, but on sites like this is different, unless you really want to make them friends only.) When I'm looking for a journal to add, I like to be able to read a few posts before I add them to make sure that I have interests in common with the journal's owner. When all the entries are private, you can't really do that, and as a result, I tend not to bother.
