Status Not Vulnerable

Nameserver

ns1.bigcommerce.com.
ns2.bigcommerce.com.
ns3.bigcommerce.com. 

Explanation

It's possible to create an account here. To add a custom domain is required to upgrade to a paid account (starting at US$39/month). The site checks if the domain is already taken by another account, making it not vulnerable, an edge case might exist but I couldn't find more examples to check.

Added this to the main page today. Sorry it took so long for me to see this.

I appreciate your post and comments on other services' vulnerabilities!
