The VPN block kind of seems unreasonable. I’m using a VPN provider that also provides email security (I’m not going to say it because that would be advertising) because:
I’ve seen Glitch Projects that are IP loggers
I’ve also seen Glitch Projects with their database hacked.
I’ve seen Glitch projects with just people who sell advertisements (those therealsuntrust.freebankmoney sites, not a real URL because the TLD is invalid)
I do see why they have it because of D(D)oS attacks but people could make their own VPN or use a bad ISP which puts your location across your country (example: Savanah, GA -> Sacramento, CA).
Odd, this usually only happens when I access glitch sites through tor. Maybe you can email support and ask if they can unblock your ip.
Can you see if other AWS based sites work like pythonanywhere.com
