No. In no situation should you even "consider" clicking the attack button. Let them kill you, even if you have a stack of diamonds on you. Any PvPing near the portal is illegal when one player has just entered the room. There is to be no confusion of that. (Any lost items can be force dropped by an admin)
I'm sorry to dig this up again, but I've read this whole thread and I've seen all possible answers. I'm completely confused now. So I'm gonna describe what happened to me and I hope any of you will help me with a straight answer. I've discussed this in the chat and I got all kinds of answers too. What happened is this:
I entered the nether through the portal near the central spawn (new as I am, I intended to harvest blaze rods and glowstone -- I know now that was kinda stupid and naive). The moment I entered the portal I was attacked (within a couple of blocks from the portal (2-3)).
As far as I can tell that was illegal right? I'm not looking to get my stuff back or anything, but the one who did it (won't state the on the forum), told me repeatedly that it was all legal and normal. A lot of ppl on the chat mentioned "Everyone is doing it, or at least 1/3 of the population". So I still don't know the truth of it.
Oh and btw, I didn't fight back in any way, just ran for it, but he was faster, I suppose through use of a speedpotion.
What bothers me is that I never got the warning, maybe I was blatantly ignorant, but there's no warning sign near the portal, I checked that pvp was off in my case. So I assumed I ccould at least enter safely. Please help me out here to get it straight!
Thanks for any thoughts on the matter in advance!
