Fun fact: telling the guy saying it's gaslighting that it's not, with your reframe of reality words like "fun fact" are gaslighting.
I've found gaslight-positive people who go on "vibes" are indeed still gaslighters. Abuse is abuse. You can justify it with "vibe check" and "they don't want you around" all you want - does my not wanting you around and treating you poorly make it any less undignified and abusive?
Being told to leave is not abuse. Being told to leave is not gaslighting. Being told it's vibes based moderation is not gaslighting. Using weaponized therapy speak is annoying, by the way.
Anyways, they are very much saying to you, I don’t like you and now I would like you to leave.
And to answer your second question, if you ran such a community, I probably wouldn’t participate! Easy!
