While you'll find girls real girls on Tinder, many of those profiles of hot women that you see could very well be fake. There are a range of different signs that you can look for in order to figure out whether a profile is real or fake. In case a profile misses a bi or an occupation, it is definitely a shady one.
Hence, avoid such profiles. Apart from that, look out for keywords and the style of language that catfishers tend to use. If a woman is acting weird, chances are that it is a fake profile desperate to trap people.
