I don’t think they block VPNs, they just use Cloudflare which often ends up being shitty. I iust tried 2 servers from Mullvad, and it works fine.
But I think it kept blocking me when I used Lifecell SIM card, like many other websites behind Cloudflare.

At this point if I see CF page I iust leave. It’s not worth waiting to see if the captcha let’s you in (most likely not).
