I saw this in another community:
Recently many of the large communities on LJ have been hacked and malware/viruses have been posted in entries to the community. After the person hacks the community, they post an entry claiming that the community is closing down and provide links to new sites. These sites contain malware, keyloggers and viruses. Do not click on them.
The only people who would post ANYTHING about this community's status would be your mods. Under no circumstances will this community be closing. If you see a post that says something like this, please immediately contact a moderator and let them know. If you see a post of any other kind that makes you suspicious, contact the mods. If it is a mod's journal that gets hacked, hang on and let the other mods deal with LJ and get things back under control.
Here are some things you can do to protect your personal journal from hacking:
*Clear out any email addresses you no longer use from LJ's records.
*Have a strong password. Don't base it on your email or username or anything someone could find out. Make them long and random, with numbers and uppercase and lowercase letters. Consider changing it on a regular basis.
*Set a secret question so that LJ can help you regain access to your account if anything happens.
