Rust Prevent building near spawns

We need a plugin that prevents players from building within 200 meters of their birthplace

 

The problem I can see is that Person A spawns in one place then Person B spawns. Person A and B are friends. Since Person A cant build with 200m of his spawn he just runs to Person B's spawn point and builds... As there are groups of spawn points and its random each time I really dont see this working. I would suggest searching up Random Spawns on google as it will make player spawn randomly all over the map (not just the coast) and it removes spawn points that are within 10m of a player build structure.
