Several things I like to mod in/out

[Docsavage1]

1.)     Blacklist certain items, or reduce the loot table drop rates to zero maybe. These items aren't craftable, and never drop, however they do randomly become available from "secret stash" at traders.
2.)     Restrict items players can sell in vending machines.
3.)     Restrict raid hours (damage to player structures.
4.)     Provide raid protection based on level discrepancies. EX: player "A" is level 45, player "B" is level 75, player "B" cannot raid player "A".

Any advice or help with .xml and code would be appreciated. 

Thanks in advance for your help!

Appears you are looking for solutions for a PvP server.  There are server manager tools that include most of that functionality. 

The 7 Days to Die Admin Coalition has a Discord server with channels dedicated to many different tools, so you should be able to get a good idea of what is available, and what will fit your needs.
