Top 100 is fine as it is. The fact that some people are using it wrong doesn't mean that it should be out of order or what ever.
When people are trying to reduce a price for example when they want to buy your pin and in order to achieve that their argumentation is the fact that your pin is not listed to top 100, who is to blame? The potential buyer or the the top 100 list?
Top 100 should not be used for pricing and ofcourse it should not be used for buying decisions.
At the end of the day, Who cares? You just like a game or you don't.
