Snapchat keeps Snapscores on each account, calculated with the number of completed snaps, stories, and more.  Snapchat users with a higher Snapscore are more likely to be real accounts. Moreover, a real account will have an authentic photo versus a stock photo, a unique username, recent activity, a verification mark, or mutual friends. Looking for these items on any new account that contacts you is another great way to spot a hacked account that’s looking for potential victims to scam.
