The site is being DDoS attacked again. They've changed their bot behavior since last time. I've added a mandatory CAPTCHA at a Cloudflare level. Sorry about the inconvenience.
If you are reporting a technical problem that involves the main website and its look / usage, I need your browser and operating system. "Me too" and "I have this issue" rarely never helps.
If you are reporting a Cloudflare issue, give me your Ray ID and country name, especially if it's an intermittent problem.
