Fake profiles on Tinder can be very frustrating and annoying. People create fake accounts with fake info just to try to sell something to you, or they try to dupe you. Be careful who you give your personal information. For you to know that they are fake profiles, you need to reach out first. Most of the fake profile always has a missing bio, occupation, age, and other information. Some have this information, but everything mentioned on their profile is a lie. Often times, they have just one photo that appears all professional, great light, nice hair, and sometimes with makeup and great posture to attract people. If they claim to be born or they live in the same country as you, but all their photo seems to be taken somewhere else, it could be a red flag. They reply to message super-fast or respond with meaningless messages.
They always want to move the conservation off tinder as quickly as possible. Their profiles always seem too good to be true.
