There should be zero stars available for scamsters. Seriously this should be an option. Why should anyone give one star to a scamming firm Robbing Hood which has colluded with their backer Citadel. They have derogatory term for Retail Investors - Dumb Money. Now the 'Dumb Money' has figured out the the hedge funds'rigged game.
Could you please review the site guidelines and stick to the rules when posting here? They include:
"Please don't fulminate."
That means please don't post comments in which indignation overwhelms information. That lowers signal/noise and escalates activation in others, which takes us away from curious conversation.
Visually, allowing 1 to 5 stars inflates the way ratings look, because the first star is always present, even for the worst products.
Imagine if it was pie chart or a bar chart: the lowest rating would look like 20%, not 0%.
Or imagine a product where 50% of people gave it the lowest rating (1 star) and the rest gave it the highest rating (5 stars). This would be presented as a 3/5 star item, which visually appears quite a bit better than its real rating (50%).
That's a consequence of the UI pattern - when you use the same widget as indicator and input, you need some way to represent "no vote yet" - plus, it would be hard to click/tap "no stars". It could be done better but alas, minimalism is the name of the game.
