An update about the Wayback Machine saving process.
I finally got some courage and, after thinking, searching, reading and even asking for help (a big thank you to them! ), wrote a Python script that automates that said saving process.
It's sloooooow but restartable (i.e. will continue with the first link left unprocessed), so it will take a while to go through the links @ED_Sln posted before. But rest assured that, eventually, all those links will appear on the Wayback Machine!
Right now (at the time of writing), 284 links had been processed
