how do you expect an archive to happen if they are not allowed to archive while it is still up.
I don't want them publishing their archive while it's up. If they archive but don't republish while the site exists then there's less damage.
I support the concept of archiving and screenshotting. I have my own linkwarden server set up and I use it all the time.
But I don't republish anything that I archive because that dilutes the value of the original creator.
