Basically your dad can only stay safe if
1 - he sticks with people who are local. If their profile shows they are in one city then when you email they are somewhere else, it's always a scam
2 - NEVER communicate through email or IM with anyone you have no met. Only communicate through the dating site. Only a scammer will ask you to start chattng off the dating site right away
3- NEVER give your full name, home addrss, birthdate or any other personal details
4 - If your dad is in his 60s, anyone under 50 contacting him is going to be a scam. The scammers usually don't post fake profiles of middle aged/senior women. Most scammers use pictures of models in their 20s/30s
5 - Get off the computer. While internet dating is a good way to make an introduction it's not a good way to build a relationship. Basically if the person can't meet for a coffee after exchaging 3-4 messages through the site, they are never going to meet. Move on
Unfortunately scammers target senior citizens/widowers because they are lonely and in many cases less aware of internet scams than younger people
A friend's dad has been conned out of almost $10k by some 30-something woman in Romania he truly believes is in love with him. His daughter and her brother are now filing for power of attorney over his finances so he can't send this scammer any more money
