Anti Griefing and Player Protection

I have a question for you guys today. What system do you guys use to protect your server against griefing and/or allow players to protect their land?

This can be anything from Whitelist to Factions to protected areas, just share what you do!

 

Users protect their land with diamond swords.

If a griefer comes in, they kill them.

 

LogBlock. Rolling back takes seconds, the only way to bypass it is if you use worldedit, and if an admin goes crazy and starts griefing with it then I'll ban them and revert to a backup, as I have a cron set to zip up the server and archive it every 6 hours.

Edit: Lolz, 1GB world size, but a 90MB LogBlock DB...

 

worldguard. I've got a setup that lets people claim regions as their own up to a certain max block volume. Love that worldguard.
