I have no idea of how interested people in here would be in this kind of stuff, but I recently started trying to find some old YGO websites on the Wayback Machine (like Geocities stuff from the very early 2000s plus some news sites and some peoples’ personal blogs) and started putting some archive links to them on Fanlore!
It’s not all of the ones I found, but I tried putting only ones that were still kinda readable (some had some stuff on WM but were too broken).
There is some cool stuff in there, I recomend some exploring to anyone who was in the fandom back then and wants to reminisce about it, or is just curious like me to see how people did fandom stuff before all fandoms kinda migrated to the same 7 sites.
Here are some pictures if anyone wants an idea of the kind of stuff you can find there:
