The person behind the account had to even purchase a copper membership just to make the announcements? Who does that?
I ought to know this, having been here so long, but maybe it was so that he could post that image? I think that's one of the restrictions a copper membership lets you side-step.
And I just read that announcement again; though I don't have any doubts that sinbad was seized, some of the wording there was just weird--even the first line:
To all criminal users of former mixer Sinbad.io
What kind of official statement starts off with what amounts to "Hey, all you criminals!"? And this, too:
We urge all criminal users and admins of mixers to cease all unlawful actions immediately. Persistent engagement will lead to severe legal consequences.
That has nothing to do with sinbad. It's just a general threat. So I've no clue what motivated the person behind the FIODNederland to post that, but it just looks bizarre to me.
