I still don't quite get why people would want to disclose real private message anonymously on the internet. It should be common knowledge that nothing is ever 100% secure. It's all about the amount of efforts people are ready to put in order to hack it.
For me it's a pointless app, with a hack that require way too much effort to get such a small value. But that is nonetheless a vulnerability and I agree that this reveals some neglecting from Yik Yak engineers.
It's a big fail for them to be advertising privacy when they don't even check the security of the 3rd party tools they include in their flow.
This should serve as a reminder for the rest of us engineers to never blindly trust 3rd party tools and always cover your ass! Thanks for sharing :)
That's not the point of Yik Yak. You're just broadcasting to the community, and rarely is something super incriminating posted, at least in my college's community.
