I sent this on Twitter but saw that I was still signed into the site on my phone, so I'll post it here too.
The site says I've been locked out of my account. I tried to sign-in on my desktop (Firefox), but each time I tried it said I needed to confirm I wasn't a robot. No captcha form was present nor was any other sort of form to prove my humanity, so I tried logging in a few more times.
Now I'm locked out of my account which is obviously web browser agnostic.
Let me know what I need to do to resolve this issue.
