Hi, it doesn't matter how careful you are, people metagame & having ''some'' extremely loose RP reasoning such as: "We LARP Christian Nationalists" in order to nearly always overcome the barrier of generating enjoyable RP for your victims (read, the players you are permanently ousting from their own community) doesn't exonerate the poor attitude most players have around "catching spooks".
Creature RP has a place on the server & it is written to allow fantasy exploration of common villainous tropes. The glaring issue in power dynamic is a lack of group OOC planning on the part of MA, FA, and CA holders, as is the opposite case with human nations - they are often entirely driven through discord.
If Creatures could get together en-masse through national discord servers & burn you at the stake while also ejecting you from the entirety of the community, I am sure they would. It would probably be a better story than another player who just wants to LARP dracula being forcibly ejected from an RP group because a guard was told in discord voice-chat, "Salt them, salt them!"
It seems your OOC attitude is leaking quite a lot into IRP, or vice versa, though it can be hard to tell with these gymnastics. These characters often have quite a lot to provide in terms of RP other than simply hanging around waiting to die. It is exactly this no good faith attitude wherein other players are perceived as your "enemy" for holding an MA that drives the constant update of lore to evade asinine & overly memed "Spook-Testing".
There is a mindset of pure, flawless character logic. Most humans abide by it. This means if I emote ANYTHING about being creepy AT ALL, the salt's coming out. No wiggle room for tropes, themes, collaborative writing, or investigation RP. Why would they need it? Why would they need to think? They have nothing to lose by just salting every single person they see.
Much the same as other "random" policies in the real world that claim to be fair & unbiased, people do not "randomly" start salt-testing unless they are quite confident OOC they will find who they are looking for. I have even seen human players declare "Salt test, salt test!" and then take someone LOGGING OFF as a reason to find them later, because they "clearly escaped the salt tests!" Funnily enough, they were a vampire.
This is bad game design, simple as.
As an addendum, the solution to this problem is simple!
Create alchemical salt that fizzles in everyone's blood. Go into the human capital, salt test their popes & such with it, and when they don't burn these people alive, we'll all know what the real issue here is.
Addendum 2: Took me all of five minutes.
