It's pretty much the opposite. Bitcoin transactions are public but don't reveal personal information. All this "digging" shows is that multiple addresses are controlled by the same person but doesn't show anything specific about that person. Unless by "personal information" you mean sockpuppeting, which is what's going on here. Sockpuppeting, attempting to do a fake trade, getting busted, lying about it - such a trustworthy person you all decided to put into DT1.
