From what I gather, and can guess at, here are some possibilities.

If you die to a group, several items are probably going to be taken, if you get back 80% of your items, that's pretty sweet.

It's one thing if you are chased down and attacked by a group, it's another if you roll up on them, and get steamrolled.

If you die to a group, they return almost everything, and you show up a second time, with an even bigger mouth than
the first time, all the while following them around ranking trying to pick up disarmed weapons, and blatantly saying so,
they will probably develop and OOC distaste for your roleplay, and be a bit more ruthless if you stick around.

That being said, try not to cuss out the player that made it a point for his group to return most of your things, on top of
that things that were traded out also, rather than use them for heals/trade/coin.

I try not to give characters away, but givin the timing of your post and your obvious frustration, I would just like to help a little bit, and only ask you offer me the same OOC respect in not pointing out particulars.

Had you not cussed me out and told me what you did, I would have probably taken nothing, but instead, you went OOC, cursed me, (if this is said situation) and rather unintelligently came after the SAME group that steamrolled you with less power than you had the first time. If your going to be cheap and follow a group around as a ghost to pick up disarmed weapons, you are probably going to be treated in a cheap fashion.

Take a break, log off, or regear, don't keep suiciding yourself into a situation that leaves no out (for RP sake) for the other character to *not kill you again, at the same time pissing said player off with OOC disrespect and then wonder why you were kicked in the nuts.

Just think about what happened, how you acted, and how said group reacted, and think if that was really logical. Don't go thinking is this what I wanted to happen, or intended to happen, or think *should happen, but did I walk into my own wall here, and then punch it a few times to boot. Then, go wonder why not only your face hurts, but your hands broken too. Just think about it eh?
