Did you know that scammers use this tool as a way to pull you deeper into the scam and convince you that they are real? They are experts at manipulating the video so that you actually think you are talking to the love of your life! They can pause the video, look like they are typing, make you think that this is a real person that you are talking to, and thereby convince you that they are who they say they are.
Here is an interesting article that tells you about the way it works:
As you can see these criminals are very clever. They can trick you into believing them, so that you are sure that this person is for real. They steal footage off of webcam dating sites and use it to fool you. Not only that, they are making a victim of the person whose footage they are using, who has no idea they are doing it.
As the article suggests, a way that you can catch them is to ask them to do something, such as touch their nose, or show you a little of the room they are in, such as a painting or picture that may be hanging on the wall or anything that will cause a reaction from the person. If they don't react that is definitely a "red flag" that something isn't right. Often they will pause the cam when you do this and claim that something is wrong with the webcam.
That is definitely the time to pull the plug and delete and block them.
One rule of thumb is to never WebCam with anyone that you don't know. Don't be willing to cam with just anyone until you have gotten to know the person very well and are sure that they are on the up and up.
The WebCam experience can be wonderful with your friends and family as it does add a personal touch that type chatting and email doesn't, but just make sure that it is a safe experience also.
