Perhaps some naughty mod whitelisted a bad email service.
Well I won't name the email service I used but it worked
it's not a whitelist, I used a temporary email service for an account a week ago
btw mods should whitelist yandex if they haven't already it's probably the single most popular webmail service in the Russian Federation.
tbh there's a really simple bypass I'm surprised none of the major trolls have picked up on it yet(at least, afaik.)
It's a whitelist not a blacklist, afaik the original whitelist consisted of:
gmail hotmail aol live yahoo
and I think all edu domains were whitelisted as well?
Just curious, what email domains are blacklisted besides the obvious ones like 10minutemail, which everyone on the planet probably blacklists to prevent trolls?
When you make an account here:

Your alternate account inherits your main account's email address. Since your email domain is blacklisted, the process fails.
You need to log out and register a new account at the sign up page.
Afterwards, link your new account to your main here:

You have one too many a's
