A snapchat user can have "Who can send me snaps..." set to "My Friends" (this is the default option), and then they have to accept a friend request from the pug before the snaps go through.
That should possibly be <cynicism> rather than sarcasm.
I think it's not a valid concern though... The maker of this app would gain no new information. If the mobile numbers are already leaked, then that information is already out there.
At the most the app maker would be able filter down to the list of snapchat ids which also use hackernews... and this would be less and less accurate as the app spreads and is reposted on other social networks.
There is something going on with pugs. Since getting one we've discovered some sort of cult following - in which we've become victim. For instance, one night I couldn't help myself so I hacked up a quick app - pugrodeo.com for posting pug photos.
OP here - it's just an idea that I had at work following GibSec's full disclosure [1] of Snapchat's (ostensibly) private API.
Pugs are a favourite and long-running meme, and Snapchat is very much a part of current internet culture, so combining the two in a new way seemed like an interesting thing to do.
