Ridgefield Police are offering some internet safety advice for people on social media sites.  Police say users should be aware of commenting on posts that ask questions such as "Who was your 1st grade teacher?", "What was your first car?" "Who was your childhood best friend?" and the like.  Ridgefield Police say they may be fishing for password recovery answers because those questions are asked when setting up account security information. Hackers can use the information to get into current accounts or open up new ones in your name.  Not all of these types of posts are scams, but Police say it's good practice to remain vigilant.
