In the article,"Snapchat tweaks security after massive hack", by Doug Gross, he explains that the creators of Snapchat will add in new privacy features since many hacked into others exposing usernames and passcodes. There is a website called snapchatDB.info where hackers post the users they have hacked. The website was susended and then was back on but was "partially disguised". When the users were posted on the website the hackers would use, they'd use the usernames posted and snapchat random people with a slightly different username with a different number at the end.
