Should I write where I work on Upwork?

Question

Upwork

Hee. I work unofficially in an Estonian company remotely. And I'm a little fed up already, I want freedom.
And now I’m sitting filling out a profile on Upwork, I stopped at filling out the work history. Should I write to where I worked but unofficially? Is this somehow verified? Is this section important at all?

Answer 1

The more the profile is filled out at the beginning, the better. How will you be checked whether you worked there or not? If the work is related to what you are going to do for upwork, of course fill it out.

Answer 2

What is the difference between official work and unofficial work?
Well, whether to write or not cares, in fact, only your current employer
