Maybe the operators have been arrested or something and are unable to get in contact with Royse? Maybe arrested for something other than mixer being seized, maybe it's nothing at all. You'll all just have to wait for an announcement from them or the manager.
Trust me on this, if owners of this services was arrested it would already be everywhere in news and they would stick big warning message on their website.
That doesn't mean agencies didn't try to track, catch, arrest them and shut down their servers many times.
But If website is not working for days than it's not nothing
A similar thing happens with the Unijoin mixer. The site is unavailable, as are other channels of communication. The manager just closed the campaign and removed the links to their services because he has no contact with the team.
Yes I saw it, and this two mixers have nothing in common, they even had different managers for campaign in forums.
I hope nobody lost coins when this happened.
