It'll sort of die, you can't access them directly but if you take the link and paste it into discord (like one with just yourself) then it'll still work.
Tbh I am even surprised those links were a thing to begin with, at the end it is mainly to share stuff on their chat platform, they sort of allowed that, but feels weird that it was a thing to begin with.
What? Discord isn’t meant to be a media hot linking service. They’re literally doing it on purpose, to stop people from doing what this person is doing.
This isn't stopping people from sharing discord media links though. It just means that others who did not share the link and cannot do anything about that will see broken images/etc. in the future.
