If that's true, I think calling it unprofessional is being kind, as 3I themselves were telling people to mine elsewhere until everything got sorted out.
I don't think so.
I was mining there, then I switched, then I came back until BigZim said to switch. I got paid on 4/6 and 4/7 (which are the first links) then I got paid yesterday for everything else (last link above). I had about 5k in total. Got everything I was due.
Those who are crying, maybe they were short changed, maybe they are a bit confused, maybe both. But BigZim isn't a scammer or thief. His pool grew larger than he could manage. But he did help get Raven going, so don't hate on him.
In hindsight I think Zims advice was wrong to move pools. We were lucky(or stupid) enough to keep mining on there and keep our shares relevant compared to others that stopped. Was Threeeyed PPLNS do you know, I think the majority are now?
...if that was the cause of the missing shares just after the first manual payout.
