He had deleted the original comment, but someone had replied and copied the text. He subsequently posted an ad for job postings with the same username and his personal email address (I think rossulbricht@gmail.com).
Basically, he was about as sloppy as it gets if you're running a criminal drug enterprise. Also, his confidant, Variety Jones/Cimon, hinted that he had done some research on Ulbricht and found some stuff. He was absurdly cocky about evading law enforcement. Makes you wonder if he has some kind of psychological disorder.
HN has a timed limiter for nested replies that grows in length depending on nested depth, mainly to stop flame wars. You have to wait a few minutes or take the hint that the thread is getting too deep.
Interesting workaround, but that doesn't make what I said untrue does it? It just sounds like they put the MVP in and never completed the functionality.
There is no source on that because it isn't true[1].
Ulbricht was found via the server - all evidence that came as a result of that (including the laptop) would have been dismissed if a 4th amendment appeal was successful.
The only evidence found outside of the server chain was the posts to the Shroomery and Bitcointalk - and as the link in grandparent comment points out, this is not sufficient probable cause for a search warrant (and a search warrant on the Gmail in any case would still not have linked Ulbricht to DPR sufficiently)

> The arrest of Ross Ulbricht got its start when the FBI somehow discovered the real location of the Silk Road server in Iceland.
and
> Every shred of evidence except for two “hey, I found this site” posts derives solely from the server seizure.
