The thing I don't like here is that you have to a third-party website (which I don't know and don't trust) to see those results , nowadays everyone should be very careful what he is doing.
Of course there is impossible to create such service without "third-party website". I would be glad if the forum engine had bb-code like
[top_quality_posts time=1day][/top_quality_posts]
But unfortunately there is no such code. So I have created the "third-party website".
In addition the controversy with you account, you choose a bad username. It was a clever way to trick the system for sure.
You are wrong here. If this username posed any threat, I would have been banned for a long time.
This is main difference: My rating contains not only topics but posts inside too. Moreover, I do not think that the topic activity is an indicator of quality. If someone will create topic name like "100 BTC for everyone" with the post inside like "This is a joke. Haha" then this topic can be quite active.
My rating is based on several criteria. Main of them is the post length. There are other criteries too.
