That's known. We know The Sceptical Chymist. But majority is doing this for getting into DT despite using the system for the purpose it has been created.
I have got one exclusion from an user who is in my trust list. I don't bother about that either because for me, his feedbacks are useful. I want to see the feedbacks he sent by default. That's what matters to me. That's why I'm not going to exclude him unless he turns into someone like Ratimov. That's how I use the system. Well, if everyone used the system for the same purpose, I believe we wouldn't have heard someone saying it's a joke. By the way, as pointed out above, if someone like you who understand the purpose of the system and understand how it works, opts out them from the system, the system will look more of jokes. That's why it's important to use the system for people like you and others who understand pretty much.
