There is a high chance that account
FIODNederland is legit because:
The account was created 2.5 hours before fiod.nl published this article, and posted about it 6 minutes after publication. [Quote from

and theymos cashed their copper membership fee

Just came across this post and now I wonder who would put up that post. I mean the timing that Synchronice mentioned is very interesting, the account being set up as a Copper Member is very interesting, and the likelihood that countless of accounts here work on behalf government agencies is quite high, isn't it?
Interesting "coincidence".
What does "Copper Member" mean? Does this forum have a paid subscription or what?

For a small fee you can set up an account that grants you certain functions a newbie account wouldn't have. That way you can post images, like the account did with the website of the seizure. It's almost granted that this person understands Bitcointalk relatively well if you also take into account the timings, like the setup of the account, the paid Copper membership, the post and the publication of the article talking about the seizure. Could be someone from the investigation team that worked on the Sinbad case.
