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
Most of the free VPNs I tried are slow and recently had database breaches. None of them worked on Glitch. Almost all of them had advertisements (and I would not like popups while surfing the web)
