I think now we should accuse them for running a campaign without paying. I think that MASS is also a scam project which is created to steal people money
Probably you are right.
Running this campaign with the intention to avoid payment is very very unfair. I've weared mass coin avatar for many weeks, as may users did, and received nothing. The user Chuck, wrote that mass project was a scam... probably he was right too.
One strange thing is that pianist (the op user) has a good trust reputation... is very strange that he get involved in this situation.
This is very sad to me.
