Abyss -random attackers + swearing words :/

[bloodrops]

Yeah, it seems like I'm encountering pretty strange people a lot these days...
The story is like this:

I was on my level 29 fighter, grinding in dungeon with a party and came across some other people, and partied up with them (ill name them so it's easier, Cleric1, Cleric2, Fighter1, Mage1). After about 20 mins, a cleric and a mage comes along, and randomly starts to attack Cleric1. My party was busy with the big mob, so we didn't really do anything. When Cleric1 was revived, the cleric/mage came back again, and attacked.

So...I killed both of them :/ I don't attack people in abyss, unless the opponent attacks me or my party member. All I do is retaliate. Then the mage starts to swear at me :/ I thought...'ok...lets ignore, one of those people..'

After a few mins, my party went towards the gate to restone..and they were there, and started to attack us *again*.
So like I did before, I killed them because Cleric2 and Mage1 died. So they swore at me again on whisper. Hmm...this time, rather than ignoring, I told them that perhaps they shouldn't have attacked us in the first place - because otherwise I wouldn't have attacked them. But they didn't care, they kept on swearing.

When I came back last to abyss after restoning, I found out that they have killed Cleric2 again. So the same thing repeated...me killing them, them swearing at me.


I realize that abyss can also be a pvp zone, but attacking without warning, or even asking is rude...isn't it?
I know in lvl50-59 abyss, and even in lvl40-49 abyss, things aren't quite like that. People tend to say 'hi' or if they really wanted to pvp, they'd ask. But this cleric/mage...they kept on attacking FIRST, and swore.

I took a screenshot of the conversation...Should I be reporting these two? They said some nasty words that really ruined my mood for the day. Perhaps I should've blocked them :/

I mean...what have I done wrong? I surely couldn't have watched and let them kill my party, some whom were my friends. ugh...
