I mean, I kinda understand it. The proposal of the platform was to promote overseas hiring. The companies hiring would help with visa and relocation costs, so I thought that it was fair for them to bet they hiring money on a promising candidate. With just the information on my resume I don't think I would be able to prove that I could write clean maintainable code. All projects that I had on my resume at the time I couldn't share, because they were real products from real companies.
