Just to add to what 6457786 said: You may see all them youtube videos showing Force OP, but ALL of them are fake and are viruses, because it cannot be done. Ask Dinnerbone (here), Ask md_5 (Developer of Spigot, here) even ask the developer of Lottery (here). It just cannot be done from the client. Why can't the client just demand OP status?
Because the server sends certain code to the client, telling the client where a certain player is, where blocks are, etc. and the server receives certain code from the client, such as block interactio...
Well if he keeps logging in and getting kicked....that would mean he isn't hacked because the person doesn't know the password. For instance anybody could log into an account and do that. So unless the person is lucky enough to guess the billions of possibilities for passwords, Tinysushi is safe.
the /votejail command can be abused easily.I also thought about that before but..meh people can abuse it so i don't know about that.It would be really cool to have 2 more Jrmods because there are times when no mods are on and there are like 5-6 hackers at pvp and such. I'm really sorry, I can't be online a lot for these upcoming weeks. I'm usually on for half of the day but some things have occurred.
The lottery, just like the server is 'unable' to be hacked. It should be called cheating or misleadin the server, not hacking, cause even a minecraft server being hacked is illegal. It's hard to explain, but hacks don't exist. Simple way - Server sided hacks DON'T WORK!!! Unless you're some crazy hacker that can hack your way into console, but that would lead to things much worse then "Lottery Hacks".
Here's what's been happening in my lottery life - Put 130 mil --> Lost it to a guy with 20 mil Put 80 mil --> Lost it to a guy with 5.5 mil Put 60 mil --> lost it to a guy with 200K Don't feel bad about your losses.
