I'm currently using
ljarchive to archive my journal. As you probably know, I already flock a lot of my personal posts, and I don't friend everyone who friends me. I use filters depending on how much I trust people. My fanfiction is unflocked.
This won't be changing. Mpreg and being a homo isn't illegal in America. Yet.
I have a greatestjournal at ladydreamer (surprise). There's nothing on it, but I might try to copy fanfiction over there.
This has been a public service announcement of your emergency fandom system. :P
