On paper, how it seems to go is that person A has archive link and sends it to op which they then upload using a different file host to prevent too much traffic on the original link which could close it.Is it not Possible/allowed to share their actual archive links here that they've posted on their patreon/subscribeStar?
There are patreon posts that mention the archive links are lists on the Members welcome page description.
Letting everyone into the original link could cause the original creator to take drastic measures that make distributing that much harder from the high increase in traffic or the occasional rat/asshole who reports the original link shutting it down for everyone.
So while simply posting the link is easy, that ease of access is leaving the door wide open for a ton of problems. Unfortunately, some people here don't realize that and think with their dicks before their brains.
tl:dr: Having a separate file host from the original prevents problems on the original links
