Re: eXch - instant exchange BTC / LN / XMR / LTC / ETH / ERC20
In the case of Sinbad, it appears that the entity is a group of hackers funded by a government or organization, so they were not able to do much, especially since the service is a renaming of a previous mixing service that was operating on the forum.
Let me see if I understand well what you meant: are you saying that FIODNederland is a group of hackers? Not a user created by Dutch authorities?
I can't be positive its not but I don't think the US government would do things like that as that would be considered entrapment. Its true that they (US + Netherlands) briefly took over Hansa market after AlphaBay was shut down - perhaps the most famous of all bitcoin/darknet "honeypots" - but they only used evidence gathered to prosecute vendors on the market who were already active.
By setting up a brand new site and enticing users who may not have otherwise wanted to mix their coin, the feds run afoul of entrapment... certain arrests wouldn't hold up in court, and thus it would be a waste of money/resources.
Who knows for sure though, anything's possible, and I'm no legal expert.
