Ultimately, this is only a warning at this stage. Nothing happens until this repeats itself too much.
Remember Upwork is drowning in freelancers and needs to attract and keep paying clients.
Poor outcomes piss off clients and pissed off clients will use the site next.
Does Upwork even consider that the bad feedback might be unfair?
If people are careful when choosing clients, "unfair" poor feedback will be relatively rare.
There are safeguards in place when a client has a history of poor outcomes. Feedback from such clients is excluded from the JSS calculation and would not trigger that email.
It's really all not that dramatic.
Huh?
