Ravi Does Upwork even consider that the bad feedback might be unfair?
I think the main thing to bear in mind is that it applies to everybody, making it entirely fair. We're all in the same boat. It's true that somebody could get unlucky with a bad client for the first letter, but it's much harder to use that argument if one triggers it again within 6 months,
The more I think about this the more I think I like it even if I do trigger the letter occasionally.
