@yumdelish - It's a sad fact of life that crooks and criminals seem to keep up with cultural changes, always looking for an oppportunity to cheat someone. Of course cyberspace is no different, but there are a few easy ways to protect yourself from Internet fraud scams.
The first thing is to approach it as if it was regular life. You wouldn't walk around with your name and address on your house or car keys, right? So why have all that information as an email signature or on your social network profiles?
Also, you should keep an eye out for small details. Any website that requires credit card information should have a URL starting with https, rather than just http. (The s stands for secure.)
Emails from anyone official, (or their websites) have a personal domain name. So your banks address would be smithstreetbank.com or email@example.com. Phishing scams can't use those so they will replace part of it. Many people don't notice those small changes.
I hope these tips help to reassure you that there are ways us regular people can do our bit to stop Internet fraud.
