If the aim is to keep web archive links, IMO, we just should mark them as ENDED.
The wayback machine links should be automatically displayed in this case.
- Right now they are already automatically displayed when you use ALL LINKS user script
- In the future, I think it would be a good feature to integrate into MBS itself
But we should really not manually input any wayback machine URLs, it’s counter productive and endless task (imagine if their format changes or if it migrates to another site, etc.).
