Unfortunately no… I wasn’t thinking and reloaded the server after I banned them and lost the logs, but while it was going on I was taking a look through console and in my logs, but didn’t see anything that stood out to me.
They all had default permissions which doesn’t enable them to change their gamemode and it’s impossible for them to get OP since you need access to console. They also tried to break my block protections, but couldn’t. They were only able to do damage outside of spawn.
At first they were just flying which I assumed was just a fly hack until they started laying down tnt that they didn’t obtain legitimately. When I switched them back to survival mode and they fell out of the air, so it wasn’t a fly hack they were using it was creative mode.
