I believe that in regards to the case you are talking about, everything that could've answered was answered already. There is little or no point to start a new round of questions that were answered previously.

The reason why I have mentioned that forum member yesterday's news related to a mixing service listed on this forum.

Also I have my own reasons to believe that account belongs to the actual agency, taking into consideration the same cybercrime investigation team behind that arrest not only works for FIOD, but also Dutch police which is known for communicating with end-users via various community channels, including spinning up dedicated .onion links for their operations. I am aware of every single operation that was performed by these two agencies and how exactly they performed, because all of that was publicly available during the past events and I witnessed everything myself.

For example:



[original at tor.ink] [oshi.at mirror]

When the event that this screenshot represents happened, similar accounts were registered across some darknet forums throwing similar messages what FIODNederland left on Bitcointalk yesterday. These agencies are known for their non-standard community communication practices.

There is a live version of that site still: http://tcecdnp2fhyxlcrjoyc2eimdjosr65hweut6y7r2u6b5y75yuvbkvfyd.onion which is an actual site that belongs to Team Cyber Enabled Crime and Dutch National Police with valid PGP signatures.

I also believe that FIOD's department responsible for yesterday's takedown consists of the same members who were/are working for politie.nl back in time, so it's all just different branding from the same entity, because the methodology involved is identical and they already have a circle of famous people working in this field. You can find many of them on Linkedin.

And by the way:


This indicates that they are quite open-minded, therefore it wouldn't surprise me at all if FIODNederland is legit. The only thing that actually disappoints me in that quote is Tor written erroneously. Guys, it's Tor, not TOR, ffs.
