Has anyone heard of etherfluent?

I got sent a discord message saying I won some ethereum. It told me to create an etherfluent account. Which I did. The code they gave me in the message shows that it gave me ethereum. Now it's telling me in order to withdraw it I need to deposit $620 worth of bitcoin. This seems really strange. Doesn't sound like a common practice.

Does it sound safe? Should I just stay away?

Any and all help is appreciated.
