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 [emphasis mine] with which you will not have problems anywhere.
That's neither the idea of mixing (1), nor is it how this mixer operates (2).
(1) Mixing usually refers to exchanging 'coins' (UTXOs.. let's call them coins) for other coins that are not linked to the ones you put into the mixer. A common use case for this: a certain Bitcoin transaction links a coin to your identity, e.g. by getting paid for a signature campaign. Both the sender (campaign manager) as well as potentially other users (in case that a public spreadsheet exists or people apply publicly with a Bitcoin address) now know this coin belongs to a certain forum user. By mixing this coin, someone can exchange this 'linked' coin for another, (or multiple smaller)
unrelated coins of similar total value.
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.
Ok And that's how this mixer works and all the ones I named above, don't try to confuse users. What bothers you is coins with dark history being removed. I don't think you are interested in mixing bitcoins, I think you are interested in farming post like the previous user. You are also trying to confuse the users and it seems very serious to me that you are trying to make them believe that it is a technical or privacy problem when in reality it is your personal matter.
(2) This mixer does absolutely not take 'Bitcoin from any source' like you claim, and that's the big issue here. It subjectively discriminates between coins and reserves the right to reject you from mixing.
Now I have to say that it is true that you are lying and it is beginning to be repetitive. You don't know what the source of this mixer's coins is, and you don't know how the Scoring system you mention works, you just have a slight idea and are making assumptions. I think you have felt bad that your list is known to be impartial and that you omit to include other services that you know well and use this same system for years.
You confuse morality with a security or privacy issue. If you don't like something, don't use it, but don't tell others it's a problem just because you don't like it.
By the way I don't see any of the mixers mentioned yet in your list. Do you have time to spam here but I understand that making your list truthful is secondary to you. And I sincerely believe that you are already spamming this thread. Although after seeing your history of comments I see that it is something you do normally.
