Why? Because the vast majority of LJ users are still high school and college students using LJ as a social interaction network - same as fandom, but in much, much greater numbers. If we disappeared, LJ would notice. For a day or so. Because maybe the site would run a tad faster with all the communities gone. Maybe. But, see, I could be wrong, so I joined it.
Okay, I'm doing the math here. 13 million livejournals. I could be wrong, but a *generous* estimate for the fen here - 10K. That's 0.8% - and even if as much as half the ljs are actually not active or just puppets or comms (and LJ just did a purge, so who knows?) - that's 1.6% of the total.
We'll basically be showing LJ that we are essentially meaningless. Go US!
And I'm not convinced that putting notices in your userinfo will stop them from suspending your lj - assuming they even read the userinfo beyond the interests.
Question - have any survivors of child sexual abuse communities been deleted? I've heard rumors, but none of the posts that list suspended communities mention those. Because if they haven't, then it's not just interests, or maybe it's a combination of interests.
And, yeah, I did clean up my interests a little bit - I got rid of "slash", "yaoi" and "pretty boys." I also added "freedom of speech." And I archived my fiction journal.
