My answer in the linked question is a viable solution for this as well.

Modify the following variable in the server.properties file:


Then OP yourself and anyone else you trust to place and destroy blocks. There must be at least one OP for spawn-protection to work.

    @Batophobia No, as minecraftwiki.net/wiki/Server.properties states: If there are no ops set on the server, the spawn protection will be disabled automatically. (emphasis mine) So you only need to have declared at least on OP, but they not need to be logged in – Zommuter Aug 2 '13 at 6:14

I hope this helped you
