The first one has an input from Theymos, so maybe he could shed light. There's not really any way to verify MB actually holds any of that... They could be donations, assuming he's even 1FRAUD - which wouldn't make sense to connect with the donation address. So many mysteries!
Oh, see I read it as someone else calling him out as being a fraud. Especially with the public note left on the payment.
Yeah. That might be it, but I almost doubt it just because the 1FRAUD address has >1kBTC received. This particularly ridiculous transaction shows a ton of other addresses in the person's wallet, many of which also had a fair number of coins, and have mixing/SDice activities tied to them.
The address activity totally stumps me, because it's almost like the person was trying to mix, but then there are transactions with huge lists of other addresses, almost like they wanted them to all be connected.
