Luminous was an admin at the time. Then, Luminous stepped down from being an admin. Then, as you mentioned, LW re-federated AN once more.
And is still considering defederating with it again as the post states. You do not get to claim full refederation as that is not the situation we are in. You are downplaying the situation.
If Luminous had merely been a mod, this could have been handled by blocking, but since they were an admin - at the time - it could only be handled by defederation.
No. It could have been handled by speaking with the admins of the other instance and saying "This is a problem." Speech is always an option, especially before taking a nuclear one.
I suppose you are calling MrKaplan a liar
Correct.
It seems his word against yours
No, I literally just presented it in the original comment.
With no evidence currently presented either way
I literally presented evidence in the original comment. A screenshot with a message from Mr. Kaplan stating that they had no evidence for what was going on, only an odd feeling. Here is the screenshot again with the relevant information highlighted.

What is your goal here on mispresenting reality so heavily?
