Inviting unconscious players hasn’t worked in quite a while now.
Regardless, this doesn’t sound like someone trying to clear out a troll that’s walling someone in or blocking resources. If it was someone with a legit concern, they’d likely be open to dialog and compromise, which they’re clearly not – they’re instead engaging in “Passive PvP” as we call it.
I’d collect what info you can and DM @Ignasi or @Hugo about it to see what the official response is. You might also poll other players on the server to see what their opinion on this is and if anyone else has been victimized by them. Other reporting the same thing, and separately would only add weight to your cause.
In the meanwhile, you might want to shop around for a good private PvE server in your timezone. I’d suggest mine, but the players I game with all love purges, so that feature is very much enabled. That said, because we love purges, there’s always folks ready and willing to help out with them so you’d needn’t fear them.
