I joined the Forest Hunters with one of my characters while I was harvesting clams in Crystal Cave. I fought someone in the Forest area and when they killed me they dropped a Prism Stone where I died- there was also another one over in a bunch of trees, where I assumed they killed another Hunter. I also invaded someone else a few minutes later and we waved at each other from afar before attacking.
Typically when I fight I won't backstab unless they are ganging someone; I ran into that when Hunting, as one had a sunbro with them and was beating one of my catbros, so I Persue'd the sunbro and attacked him so the fight was 1v1 until I managed to backstab the Master (which was actually by accident hilariously enough, I was trying to bash the sunbro with my Black Knight Axe when the Master ran in front of me and I backstabbed him by accident and killed him) but other than accidental stabs, I usually won't backstab them.
Unless something like that is going down (with an unfair gang-fight) I will usually bow to my opponents- which is kinda weird as I'll do it even while Hunting/Darkwraith invading but I've had quite a few trespassers return the gesture- those who don't I'll kill them with whatever I have, be it Persuers or Wrath of the Gods.
I'm also fond of Pyromancy so I'll use that- I have no problems with people using whatever they have on hand. I won't spam my spells though, so even if I use WotG, I will only do it if they are trying to circle to backstab me excessively.
What about you guys? Do you bow? Do you do a trident dance? What are your rules? Proper Bows?
