The photo is stolen look at the profile pic by dragging it to google

As soon as they ask for pics, money or other things it's a red flag.

Honestly you don’t ….

My intuition serves me well

Watch the show and take notes I guess lol

Hopefully you'd see the red flags

Things don't add up
The same pictures get used
Scared to video call (could just be insecurities tho)
Excuses to meeting up or you get ditched
They come clean about age or whatever else they might have lied/catfished about
Other people have the same idea about the person

Look them up

If they won’t talk on the phone or video chat. If they always have excuses about how their camera doesn’t work or their phone is broken. If they don’t give you their full name. If their story doesn’t make sense or is too good to be true.

If they have different pictures
