Im still learning but im pretty sure it's the relays that do it

Depends on which feed. Follow feed, your client sends a request with a filter that pulls events for a list of people.
Global is just everyone posting to that relay. Or a list of relays you have added.
Clients deduplicate events from people who post to multiple relays.
Relays blacklist people who spam or break ToS - not heard of many people getting blocked at this level for most relays.
Some clients do client side spam filtering based on reports from people in your friends list.
So, in global especially, it depends on which relays you use. You will only see the people on those relays. This is useful, because it you limit global to paid relays, you will see less spam because most spammers won’t pay to just get blocked.
Thanks for that!
So the relays send (or are pulled) as they are posted?
