You mean like when he created that Twitter account and I had to point out that he should add a reminder for people not to follow him with accounts they created over clearnet? Yeah, he's capable of overlooking security issues, and this feedback system creates an opportunity for several new attacks. Hiding the name is a superficial defense when purchasing stats and account age make pseudonymous reviewers uniquely identifiable. What's worse is that now there's verifiable proof of how much money a buyer has spent, and it will be possible to reconstruct their buying history, whereas before, even if people on the forum claimed they spent $100K, they could have been full of shit. Stats in forum signatures can be completely made up, but stats in market reviews are admissible as evidence in court, just like traditional paper and pen transaction ledgers have been used against drug dealers for decades. And we pretty much know now with 99% certainty that he doesn't delete any transaction info, otherwise he could not have known have many unique vendors people purchased from a year ago. A smart dealer would throw his ledger in the fireplace each week, but you have no control over this one, except to hide it.
