1. Take every username (or email) and password combination
2. Through automated means, check if they are valid on other websites
3. Record the ones that worked and abuse/sell those as well.
Then again... only a fraction of the audience is really that invested in their save games. The truly valuable stuff (relatively speaking) is all tied to mmo accounts (and therefore not stored on your PC anyway).
Exactly, it would be far more profitable for them to simply steal any saved account credentials.
From what I understand (and I have only sketchy information on this), the police were contacted, and YikYak was asked for an IP address.
However, either they refused to give one, or it ended up being some public computer (this is, after all, a university; there are hundreds of public computers on campus). Nothing the police can do about that. Even CSI's reality-bending tricks would have trouble figuring out which of dozens of people who sat at that computer might have sent the message.
How is that different from any internet communications platform? If someone hops on a random public computer, they could easily anonymously send those death threats or other nasty messages via an email, some other anonymous website/service, or even through a payphone of all things. The only thing that YikYak provides is convenience. I don't think that if there were no death threats before YikYak, that any of the death threats sent through YikYak would have any shred of credibility. Someone isn't going to say "wow look at this app that I can send death threats through, I think I'll go murder someone that I wasn't going to murder before".
I think the scariest part of all of it is that someone could easily just use my name, post bad things, and I'd take the blame for it.
