Imo, if someone in RP doesnt know who you are or why you are shooting at them, you explain, he is in a mining ship, and is not going anywhere and is no threat to you.
Personally, i have been asked many times 'why r u shootin me?', every time, you should explain who you are, as the large percentage of people you meet are nubs, and have no clue who you are. Also, one on one RP can be great fun, especially when you are teaching the other person (probably a nub) what RP is, and introducing them to RP situations.
To be honest, it is things like these that cause the phantoms to be flamed so much, to people who dont understand who they are, they just get told when asking 'they are an invite only, mostly admin faction with special guns and ships'. Now, if i were a nub, i'd think that that sounds like a poorly disguised excuse to PvPwhore with the baisically any ships and guns you want. The only way to prevent this, and the enevitable bias that comes from it, is to actively RP with people (especially in one to one situations), not just shoot them and say 'im a phantom, im here to kill you'.
As much as i respect what the phantoms are, no matter who you meet, you should RP with them to the full extent of your capabilities, not just shoot them 'because you can', otherwise you invite flames and imo have no defense. If you dont RP with someone on one ocasion, no matter how much you might on others, you will be branded PvPwhores by them.
So, in relation to this video, no matter who asks 'why are you shooting me' saying 'because i am a phantom' gives you no leg to stand on when accused of not RPing.
It does not matter who you are RPing with, what matters is that you RP.
So, yes, i think a phantom feedback thread would be nice, if at least to let people let some of their grievences out.
Edit: One more thing, do the phantoms have free lisence to shoot traders without asking for cargo/credits?
