I really urge the younger tumblr users, in particular, to protect themselves on here and choose wisely who they trust. Even if someone seems trustworthy cause your friends follow them or whatever, please think before doing things like giving out your contact info or your home address. Really, if any tumblr user interacting with you in any way makes you uncomfortable, it is 100% your right to disengage and ask that person to not follow you or communicate with you.
