"The dungeon is included in this rule."
That's the only part that I see that's new.
What if a player is chasing after hitting another person once, but is too slow, and an x amount of time passes. When will you be able to /spawn again?
Or if a player is being attacked, such as a player shooting another person with an arrow, but misses, will that count as being in combat?
What I'm suggesting is to expand on what "being in combat" is because not everyone knows exactly what it is. Players should be able to look at the rules and instantly know what is what, but there isn't really much explanation on the first section.
The second section is very specific, telling people you can't use any commands in the terrarium asides from /hat.
The third section is also very specific, stating specifically that poison, strength, and invis potions are illegal.
The fourth section is just as specific as the second and third, saying that you cannot stand around ladders to kill people, or camp there. Most players know what camping is.
However, if you take a look at the first section,
1. PVP Logging
Disconnecting from Meepcraft in the middle of combat by closing the window, or any other means of purposeful disconnection is not allowed in PVP combat except in the wild worlds (wild, nethers, end). Any act of instant teleportation, while in combat, may also be considered logging. The dungeon is included in this rule.
it doesn't really explain that much.
"Any act of instant teleportation, while in combat, may be considered logging."
"Is someone chasing you? This is also combat, if you did this in terrarium you'd be reported."
Usually when people say they are in combat, they mean it as in engaging in each other, like hitting each other. When you say "Is someone chasing you" players might not be sure whether or not it's after you've been hit or if you haven't been hit at all.
"You cannot log in the dungeon. This means disconnecting, purposely or accidently, you cannot teleport away, this has been considered logging for over two years now."
You didn't say "in combat" anywhere in this, or even in the Dicussion thread.
Because you didn't say that, people might think that you can't /spawn in the dungeon, as I asked on your profile.
I suppose it's just me nitpicking, but players might actually not realize the specifics of the rule. Most of the scenarios I listed are fairly common, and it could actually cause problems.
Even if me or you and some others know exactly how the rules work, some people who are newer might not.
