SPAWN AND ANTI GREIF HELP!!

Hey guys, I'm new to the planet minecraft community and I created a server. I just need some help setting up an anti-greif plugin. Anyone know a good one?

My server version is for minecraft 1.9.4, the latest, and I just need some advice on what plugin to get because i made a spawn and I want to claim it so that nobody destroys it.

Please help!

I'm not giving out the server address because I don't want anyone to go in and greif it!
