then banning Jambler is not necessary, since they perform blockchain analysis prior to accepting the fund and will return the "deposit" back to the originating wallet if the score [I used the word "tainted" here, though it probably not the best word to use] is negative, i.e. their origin is questionable.
They perform blockchain analysis on funds that they receive from sellers, aka investors. So, if you want to invest in Jambler.io and earn some profit, your deposited coins will undergo blockchain analysis to ensure that coins are clean. This doesn't mean that Jambler performs the analysis of coins that customers deposit on its partner mixers. You can check their FAQ and the FAQ of their partners, it's never said that coins that get deposited for mixer purposes ever undergo a blockchain analysis.
Thus, procedure-wise, whether it function like Wasabi or not? I don't think so too. They don't have the same SOP, and working on the completely different protocol.
Wasabi wallet performs blockchain analysis, that's why I asked this question but Jumbler doesn't performs that. By the way, performing of blockchain analysis destroys the privacy and the whole point of mixing and coinjoin.
