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.
And with all due respect, it's easy for you (or anyone who got what they were supposed to get) to say not to hate on him. But there seem to be quite a few people who didn't, and to tell them that they shouldn't hate on someone (or, worse, blaming them by calling them "confused") is flat-out insulting on your part.
