“Another site is already using this domain” error trying to set custom domain “blog.ultraluz.com.br” on site “focused-wescoff-032311”
Lost access to github account that we used to signup due to losing our email. 
Can you remove that site, I cleared it up from the cloudflare dns.
Hi @ultraluz! Welcome to netlify community.
I will follow up with an email to confirm and complete your request. 
hm? I don’t have access to the email that was used to signup on github so I am not sure which email will you follow up on?
I can verify domain ownership though
I sent the email to the address you use here on Community
