What country does lemmy.world reside in? For example how can I have comments of 110 answers. when I fall asleep at 10pm cst American. and wake up and have like 150?

The location of the server doesn’t really matter so when you are asleep others are accessing it. In addition other Fediverse servers also work outside your timezone. But to answer the question it’s in The Netherlands.

AFAIK USA. But I’d assume that lemmy.world users aren’t the only ones who see and comment on your posts. e.g. I have insomnia, I might comment at literally any time, and I often scroll through All.

Kicked off Reddit? A lot of people here left years ago due to their consistently shit practices and never looked back.

You seem confused about a few things:

• people from everywhere in the world can register on most websites including lemmy.world, doesn’t matter where they are hosted
• people from other instances, who likewise may be everywhere in the world, can interact with your posts and comments too

FWIW https://legal.lemmy.world/tos/ claims that instance operates according to Dutch, Finnish and German law.
