Found the cause
Added 2025-04-26 15:16:23 +0000 UTCSo it turns out Pixiv is broken. A lot of users have had the same problems that I have currently. And apparently, Pixiv shadowbans users without proper reason plenty of times. That means literally anyone can get suspended without proper reason and take away ALL YOUR WORKS without telling you the reason why.
So as much as I hate the idea, I'm gonna have to make a new Pixiv account and reupload all of my works there, one by one. That means starting from zero followers and zero commissions... shit...
There's one good news though: I still have access to this FANBOX account and can connect my new account to this one. So links will still work here, thank goodness.
All of this happening while I'm preparing for an anime convention IRL too... Gonna have to change my business card ARGHHHHH!!!
Anyway, here's the link to the new account: https://www.pixiv.net/en/users/115789712
