The instance in question was the Shota House.

I just realized that possession of loli and shotacon is illegal in most countries. I was very wrong to join that instance. That Akkoma instance is centered about such content originated from Japan or Japanese-style artwork.

The owner of the instance is visually impaired.

I was very inactive on that instance, until I deleted my account there back in October coz it would be frowned to be active there.

Originally, I discussed privately to someone on Discord about that.
