assuming the servers are properly federated you should be getting a link that is still on your server. i mean, you got to this lemmy.ml link alright at least

wait, i think i get what you mean, like if you get an external link while not browsing on your instance? you should just be able to paste that link into the search function to find your instance’s version of the post

tbf people just wanna sign up and click on funny links, not browse through 100 rando instances to find the one that lines up with their exact interests and wait for approval and worry about uptime and whether their instance will still exist in a year

That’s concerning. There’ll be a ton of problems like that if Lemmy actually sees a mass migration happen. Top of the list: what’s stopping people from vote brigading posts with accounts from different instances? I’ve had to create 3 of them just to be able to consistently access the site as the first one didn’t work and the second (this one) saw excessive loading times for a few hours.
