I designed two tests for you, which you can take and find out if you are talking to a scammer. One for Russian scammers and one for Nigerians. Please take these tests with a grain of salt, they are nothing scientific, just based on my own observations and experience, though they can give you some important clues.
BTW, if you recognize yourself in some questions LOL, this will give you a hint what you probably should NOT do, so people don't think you are a scammer. Unless you are the unlucky owner of the last name Williams or Smith! Just kidding.
Are you in contact with a Nigerian scammer
