I have a diving board asking to allow push in my land. What to do to prevent any other pushing?

[Alwin Alcott]

in general if you allow push, it will allow all push.

That diving board is evidently scripted to use the LSL command llPushObject to give you a little spring in the air.  The command won't work unless pushing is allowed, except that it will always work (1) if it is pushing whoever owns the script -- you --  or (2) on land that is owned by whoever owns the script.  If your land is owned by a group, you could deed the diving board to the group to satisfy that second condition if you wanted to.  So, your diving board should work for everyone if it's on land that you own (not rent) or if it is deeded to the group that owns the land.  If neither of those is true, then at least you can dive off of it yourself.  Or you can get a different diving board.
