So I was near his base and when i saw him I attacked 😛 I was fighting him then he stoped punching me and 1 second later he disappeared.I was waiting a few sec then I logged off (I thought I was lagging and I was killed for logging in PvP combat).
Here is the pic where he admitted it.(Teleporting in combat)
The server has plugins that allow you to NOT to teleport in combat.
The only way he could teleport was if you didn't hit him OR if you did hit him you let enough time go by between attacks that he was able to essentially "leave combat."
If he was able to teleport then he was allowed to teleport.
The only way he would be able to break this rule is if he told the plugin to stfu lol.
