What is the purpose of throwing poison on players and pvp and getting out? The players you are throwing poison on do not take damage from poison because of their SVA armor, and you do not stay in the pit to kill them. Your goal appears to be only to convenience players who are in PVP, which is trolling.
Any other attack on players when in the PVP arena results in being "PVP Tagged" which prevents them from immediately running out of the arena, however throwing potions does not PVP tag either player. You have taken advantage of that feature, and ran away after poisoning players. You have also blatantly stated in public chat that you laugh about doing it, and that you "maybe" do it to troll people. (I can find the chatlogs of this if need be.)
Kade is not suggesting that you cannot use poison in PVP. Kade is not suggesting you cannot use Invisibility in PVP. Kade is saying you can not go invisible, throw poison at people in the arena, and run out immediately after. You have stated you show up with thousands of potions to do this, and that you don't care that it doesn't kill anyone.
Not all the rules are clearly defined in the forums rule list, and many interpretations of the rules have changed over time. It is generally understood that Physical Trolling means to interfere or inconvenience players for the sake of simply inconveniencing them. Standing in front of people when they are fishing is physical trolling. Putting a fishing rod in someones head during Manapond is physical trolling.
The PVP arena is for everyone, yes. So this rule applies to everyone who tries to go into pvp invisible, throw poison at people, and leave.
It is true that you are not throwing them from the outside, because you realized that doesn't work any longer, and now have found a way around it. You are essentially attempting to bypass an existing rule.
