Well you still have the direct links, so it doesn’t make a difference.
You can use the Wayback machine addon to easily get archived links https://addons.mozilla.org/en-US/firefox/addon/wayback-machine_new/.
And a bookmarklet for archive.today:
javascript:void(open('https://archive.today/?run=1&url='+encodeURIComponent(document.location)))
Yes, the archive.today links have that risk, but not the archive.org ones. Also, you can manually modify archive.today links to show the original link.
That might be one reason lemmy.world has a relatively high domain authority.
Your 3 links won’t make a difference. Starting a trend and spreading the word will.
