Is default spawn-protection any good?

I wanted to ask if it is any good to use the default spawn-prorection radius in server.properties to protect my spawn in a small server, without installing WE and WG to protect that region.

Does it block mob griefing? Does it stop players from opening/closing trapdoors, ore use windcharges do do that?

Or is it just trash and I should use something else instead?

Solution

Use world guard
