Looks like they are using WhoIsGuard to protect the domain whois information. The terms of WhoIsGuard[1] include not violating the privacy of others: > defame, abuse, harass, threaten or otherwise violate the legal rights (such as rights of privacy and publicity) of others; I've sent WhoIsGuard an email. Hopefully they'll revoke service. Shame on the people that published this private information. They aren't hurting…
That would be Snapchat.
Stop trying to censor stuff that's already out there.
