I am not completely sure but I think he is back into the campaign. I saw this post(quoted below) on their signature campaign thread. it seems like he returned the money and is now back into the campaign.
Color me surprised. I didn't expect this at all especially after he didn't return the funds promptly. Looks like his efforts paid off. It's weird that 1xbit keeps scamming their customers regularly, but doesn't scam any of their signature campaign participants.
Another weird point here is that @galambo was admitted into the campaign despite having negative trust which is against their rules.
