I just read this on another livejorunal, posted from a comm I'm not a member of, a_ra_shi, that I thought might be of interest:
You might or might not have noticed, but in the past month or so many journals have been suspended without warning or notification by LJ. This appears to be because LJ implemented a new script to catch spambots, except this new script seems to potentially mark as spam any post containing links that go out of the site (to Mega, MediaFire, etc.) Once a journal has been marked as "spambot," it will be deleted without warning or notice.
