I like the idea of bitcoin mixers because sometimes it is needed to use these, but I hate when it is used by hackers which hide their identity in this way mostly.
That's the problem nowadays, many hackers are using these mixer services which enables them to scam and get a way with crimes.
I hope the community will come to a consensus on how to deal with these kind of cases.
I don't know how the community can make a consensus and 'track' these people mixing the bitcoins.
Bitcoin was designed as an anonymous and decentralized currency. Because more and more companies are opening every year makes the bitcoin not anonymous anymore because the bitcoin will be transferred from one exchange/company to another one.
that problem will always exist and there is nothing anybody can do about it, and you should know that it is not bitcoin, hackers and all the bad guys will always use anything for their own bad purposes.
they have been using credit cards, and money (fiat) laundering for ages and still do.
Unfortunately that's true, but I have read somewhere that exchanges does not accept or does not process these dirty coins but still there are way for these to mix and spend these bitcoins and they probably don't care about the bitcoin mixer fees.
