[Fake Buyers coming when i have a real order running?]

Hello,

 

don't know if this is a real problem or maybe it's just me. 
I'm on fiverr for over 2 years now. 
Everytime i have a real order i'm working on i get at least two people messaging me about my gig. And they don't seem to be fake at first. Having a normal conversation about the work and all and suddenly they stop answering. Maybe they went with someone else or something.

But what i noticed lately that this "buyer" are new to fiverr, their accounts are created in the month they messaged me and i looked at some old messages i got. They don't seem to have any order placed after they messaged me.

Is this normal`?
