Actually in this case the absolute best thing would be for Snapchat, Inc. to go full court press against snapchatdb.info, as what is actually important here is to communicate both the "snapchat security is a lie" message, and "companies which flagrantly suck and then piss on those who report vulnerabilities responsibly will suffer" message, rather than the actual snapchat phone/username db. Streisand will help that more than "go to this site which is really slow and download a huge file which you can't easily use to find your own number or that of your friends" (without a minimum of "how to use a computer" skill).
