I'm not sure if jeroenn13 actually had the buymastercoin.com domain.
But he was the owner of koopmastercoin.nl (which was the dutch version running the same scam as the buymastercoin one.)
Have proof in pm's but it's not in english. Although it seems like everybody already knows he's lying about it all anyway.
But yeah he definitely was involved with scamming in the same way as buymastercoin was.
And people claiming it's not a scam are obviously either involved with it or don't understand it.
As a holder of MSC it's pretty disappointing to see what has happened this year with MSC.
Honestly it's surprising to me that JR is bragging/posting about his buying/spending habits after his initial sell crashed the price of which it never really recovered. The only recovery was with the maidsafe-debacle. And I don't think you can really call that a recovery.
At this point I feel sorry for the people who have invested in this project and lost a lot of money, but also for the people who are now trying to save it which seems unlikely at this point.
They are now passed by other coins who don't have the many problems that MSC still has at this point.
I think many investors feel that they are in the same boat. We can sell now at 5-10% (or some at 2% that bought at buymasterscam.com) at the price we bought these coins or go for a hail-mary. And I hope that most investors didn't put more then they could lose into it!
