Lastly, since you are a taint proclaiming service, I had to add you to my Blacklist of unreliable, 'taint proclaiming' Bitcoin services / exchanges.
A mixer's job is not to exchange 'dirty' coins for 'clean' coins, at least if we assume that these terms refer to a coin (not) having been used for illegal activities.
Your point of view is interesting, I cannot deny that it seems a necessity for you and other users. I will definitely go through your thread to give my opinion when I have time.
You have made me think of an option that fits what you have transmitted to me, thank you for this. And maybe build something without a scoring system as an option for all those users who want to use it.
I cannot deny that many other users prefer the scoring system, but I think it would be a good idea to implement what you mention as an option and let each user decide.
