OK, so why did Hastalk close?
1. Hardware failure.
Don't think so, looks like it was hosted on a cloud service and if it had I'm sure they would be trying to fix it. If they still owned the domain they could always redirect the old domain to the new server.
Hashtalk point to 184.168.221.32, there are 300 thousand other domains from this server. Perhaps it's just a cdn, either way they would put up a simple page or a redirect to go to the new server.
http://reverseip.domaintools.com/search/?q=184.168.221.322. Done on purpose so people don't dump paycoin.
Then why bother opening a new forum?
3. Josh has been shut down.
Perhaps sec or someone has ordered he makes good on xpy withdrawals and shuts down all of his hyping websites pending investigation?
4. Josh sold of the remains of paycoin to teamxpy
He had changed his avatar on hashtalk to a phoenic, perhaps that's what he was hinting at?
Then there was the link to a tweat he posted pointing to the new forum, I haven't seen it but it's not there now and there's nothing in his twitter feed, in fact it looks like most of his recent tweets have been removed.
Something very strange going on here.
