Kill without RP ?

[Moberg]

I could put up endless skype conversations of people I know being disgusted with K'hara hunting them down or feeding regens while cloaked to people they shouldn't be affiliated with. If I had logs of ye olde group chats, I'm sure I could fill half this page with people being displeased with Nomads in general. I'm sure I could fine many links to people not liking it on the forums too, but I don't care to. Everyone has seen them pop up in the past. I used to have screens of K'hara breaking server and ID rules, but I was told to not use them and that it was all already sorted.

"I have evidence why this is bad but I can't be bothered to show it to you or anyone else. Just trust me. No really, I have evidence, I just can't show it."

If you have seen rule violations, file a sanction report and/or talk to the faction leader(s). If you've seen bad attitude, talk to the faction leader(s).
Additionally, what you mentioned has nothing to do with engaging without RP. Even if that happened, it wouldn't be a rule violation, since ID rules overwrite server rules. When you see a rule violation and don't report it, you shouldn't wonder if no steps are taken against it, as the leaders/admins are most likely not aware of it.

Maybe that is some insight for people as to why I am disgusted the Nomads are even a playable faction, and why I think they should just be purged from the game (along with some people I shan't mention) like they were meant to have been at the end of the vanilla campaign, imo.

The Nomads weren't purged forever. Juni says "They're gone, but they're not beaten" in the hypergate cinematic. This basically says that their return is certain. And the current nomad lore picks up on exactly that.
