On Wordpress.com, you can also write "under lock and key"

WordPress platform developers report that bloggers using this service as a platform for their “offspring” will be able to write “under lockdown”, i.e. only for a certain range of users. Thus, following the example of LJ and Vox, the creators of the site are trying to attract new visitors with the possibility of “private blogging.”



However, unlike competitors, the new feature turned out to be shareware: you can write for free only for a community of 35 users, and to increase the list of "friends" you have to buy a "paid account" - for $ 30 a year.
