To you, there might be "literally nothing" suspicious about it, but when that user's previous post on the forum discussed Silk Road, likely for the first time ever, a law enforcement officer, having few leads to go on, might feel inclined to investigate that individual further. Again, there's also the tiny detail about a package with nine fake IDs being sent to Ulbricht in July 2013. DHS agents confronted him about it around that time: "The photos also matched his Texas driving license, which the DHS investigators asked to see. All of this happened around the same time that Dread Pirate Roberts was discussing obtaining fake IDs on Silk Road, the FBI affidavit said. The FBI put the final piece of the puzzle in place by pulling Ulbricht's Texas driving license and comparing it with the license that Ulbricht showed the DHS. The numbers matched. At this point, it must have considered that it had enough evidence." http://www.coindesk.com/ross-ulbrichts-silk-road-head-smacki...

Lack of leads is no excuse to start digging in people's privacy.

The fake ID thing seems to have occurred after the warrant was issued, so I'm not sure I see its relevance.
