Snapchat Accounts - Hacker help - how do they do this?

[kizzoboy]

So I have two strange snapchat accounts on my friends list: huskie_snaps and sexynudebabes2.  It appears that both of these accounts function like so:

1. Snap chat users add this account to their friend's list.
2. Snap chat users that add the account send snaps to huskie_snaps or sexynudebabes2.
3. The snaps sent are automatically forwarded (i think) to the story for huskie_snaps or sexynudebabes2.

How does this happen?  I know that there are a lot of accounts out there like this.  Anyone know?

Automated software most likely.
