I have to break a lance in favor of these guys since I see your interventions in this thread a bit unfair. They didn't ignore your post, as I see they replied to you and the user n0nce, who refer to the same thread that he owns. So I assume you both have similar personal interests. The scoring system will seem bad to you, but not to other users, since you deliver any bitcoin from any source and in exchange you receive a clean one with which you will not have problems anywhere. I understand that this bothers you, but it is not fooling anyone as you try to make it appear.
You're attacking Bitcoin's fungibility while trying to use it to make your service look good. That's like misleading users who don't understand the basics of fungibility.
Here it is blatantly noticeable that it is you who is trying to confuse users about the service. Users receive clean bitcoins with no Dark history, which is what the users want. That is not aligned with your way of thinking. I understand that this is what bothers you, but it is not something negative in my opinion, quite the opposite.
After reviewing this list and its comments, I have to say it seems very strange to me that this is the first mixer that you include. Missing from that list are many services that uses the same system and are already widely known as mixer_money, webmixer, mixy, Mixerdream, Mixtura and many more.
And the most important thing is that I think you tries to make everyone believe that selecting coins is bad for users security and it is not true.
The way a service responds to criticism tells you a lot about how they operate. In your case, it doesn't look good.
The answers they have given to all users seem correct to me, they have been informative and polite throughout, Except for the comments of user n0nce who blatantly has a strange and intriguing interest in this thread. and I have to say that reading the answer he has given you has been fun and not annoying.
Also, I see that you repeat the same thing over and over again in your post, although they have already answered you regarding how it works. What inclines me to think that you have a hidden interest in harming this particular service.
I see that you are a legendary member, I understand that post farming is something natural in you.
I could not omit the fact that both you and the user n0nce participate in marketing campaigns for other services similar to this one, it can be seen in your signatures. And right now, you have the same advertising active in your firm. I want to say that you are users who are paid to make positive reviews and I suppose also negative ones, that would solve why there is no mixer except this one on your list.
I think that all users who are not 24 hours a day in this forum should have several sources of information and not only from users like you who normally receive money in exchange for X. It is my humble opinion. I have sincerely searched your comments and you are not attacking with the arguments that you have used here any of the other mixers that use the exact same system that you are complaining about. Which leads me to think once again that I shouldn't trust your selective criteria since there are other factors involved.
