anti grief and like ones that u can edit blocks and they come back if you destory them please i dont really know how to use that stuff becuase i just got python
For that you need custom server software.
People seem to get confused easily on what a script/server is.
But to just clarify most servers out there are customized, or from scratched, or modified. A script is an add-on that plugs into the original server which does not have the ability to have anti-grief (Not yet i believe.) Please look into talking to the server owners about this.
