hello bro,
I had the same experience what you had . I messaged them in telegram and it goes good. finally they asked $35 as insurance . at that moment i got smelled that it would be a scam . It was the first who contacting me for work . I was happy when i saw a message in my inbox . And i shared this experience to my friend. He told that there have a chance to fraud team and you should make the conversation in fiverr only , you don't the contact anyone in other applications .
I left that dirty team's work. after a few minutes i saw that the fiverr has blocked them .
so ,
bro we should careful to do conversations between clients toward fiverr only.
Thank you...
