yes and no, Ive just tested it both with a vpn and without, since seeing your post, turns out its DNS hijack or the site banned the IP address don't know why because I don't use exploits I genuinely paid for credits with vpn it works fine without it just redirects to another site, strange, both cloth and deep are the most accurate of the sites Ive seen (excluding of course deepnude.cc which is top notch) wonder how long it took their models to get this accurate how much training they got before getting reliable
I believe that all three sites are "fronts" for the main site that handles image processing, if the main processing site banned an entire block of IPs (country or region based) for whatever reason, it might explain why most of the sites redirect to the same page, but works fine when using a VPN maybe too many exploits users like forcing routers to change IPs with reboots and stuff like that
Yes unfortunately they do have some way to detect VPN connections so it only works if you do have an account and buy your own credits but it wont let you use free credits or at least that was the last time I checked, since this redirection issue Ive decided to not risk it and buy more maybe too many people exploited that site wich unfortunately I never tried to see the source code to see what was the main site that processed the images
