There is a large difference between "user" and "customer", the problem is you may think that you are a "customer" (or at least potential customer) of every site you visit, but this is incorrect.
"Customer" implies that there is a business relationship in play, however if it is a forum or other free resource, you will never be a customer as there is nothing to purchase. Not every website on the internet is a business.
It is often seen as abuse when a user downloads or needlessly accesses a resource (files) multiple times and website administrators often have no qualms blocking abuse, it means less load on their site's server and more resources free (bandwidth, connection slots on the webserver daemon) for other users and on top of that: potentially lowering their bill.
Coming from experience, I've seen people use download managers and misconfigure them purposefully so they open 20-100+ connections to a file feeling that the website somehow owes them that file, doing so on a webpage with a browser is no different.
