This Thing also happened to me. I am a new seller so I stay active on fiverr full 24h. One day a clint messaged me and said that he has lot of work over Image to Text.
And then he gave me number and signed out. I told him tat its out of fiverrs policy to contact out of fiverr. But he never came back. and the Next day I see the same thing tat says "xxxx001 can no longer be contacted. This will not affect your response rate".
I really has happy to see a message from Clint tough. 🙂
