I feel like catfishing is absolutely rife on here, unfortunately. It's hard to tell if it's a larger number of people or a small number of people coming back repeatedly, but in practice it doesn't really matter.
I'm always extremely skeptical, doubly so when someone has an implausible story about their experiences. I know a few regulars in chat are just guys pretending to be young women for attention or some weird roleplay thing - you can probably pick them out yourself after hearing their "experiences".
The only advice I can give is be careful, be skeptical, and don't commit to anything with anyone unless you've spoken face to face in a way that can't be faked, like live video chat. Sadly even voice calls are less than 100% reliable these days.
