mr_abel is hacking the server by saying give me vip or die, and telling us to say **** isreal, and first he tried to get money
The player cannot hack the server. It's impossible. You should take screenshots of the player's chat violations and report in the Player Reports forum.
I think he is using world edit to lag the server into disconnecting, plus he is making fun of Americans and Israel. And telling us to buy him Vip or we will all die.
He probably discovered that glitch... I really hope @CollinPotato gets some more RAM or something or this could turn into a major problem. Another way to fix it is to let Collin re-enable the 25000 block limit for WE.
