Disclaimer - I realise that this isn't that deep.
I buy and sell a bit on vinted. I always take care to leave positive feedback rather than just letting it come automatically because I feel it's a nice way to say thank you to sellers.
I was doing this just not and noticed that the person who had left feedback before had left very positive comments with 4 stars. The seller had politely enquired about why they'd lost a star and got the response Vinted "I only ever leave 4 stars because there's always room for improvement".
I instantly went to the profile of the person who wrote it and blocked them because they sounded like a nob, but is this a thing now? Meaning that some people are essentially marking out of 4 rather than 5 to prove some kind of point?
