All servers you see running are being controlled by other players. The person who is paying for the server, owned or rented, is basically God on that server.

If they are trolling you with trolls that just means they don't want you there. Nothing you can do about it.

That's simply not true. Anyone with simple mods can spawn in whatever on any server they have access to, not just the server owner. Griefers hit any servers with public passwords because they are just genuinely terrible people who only can find enjoyment in ruining things for others.
