Looking for a tool that when you ban someone for spamming items,
every item they have ever placed in that server is removed.

i have a build server and allow players to use the F1Spawn menu so they 
can practise building bases with instant access to items.

i have blacklisted all things such as fireworks, grenades, supply signals etc that
some players use to try and lag the server,  ive noticed people place things like
100 sleeping bags,  or random foundations across the map,  so wanting something
so when i ban them for spamming everything they have ever placed is removed so i
dont have to manually search and remove items.

 i thought about entitiy cleaner but some people have unfinished bases  etc and i dont want
them to have their items removed.    any suggestions are welcomed :)

Hello. There is a command in game which deletes all entities placed by a player: "entity.deleteby (steamId)".
There is a plugin to automate this as well when banning a player: https://umod.org/plugins/ban-delete-by
