Here's why I'm concerned:

1. The grandparent links to two articles as "sources." One's a guest blog by the subject. The other's a self-quote of the subject extracted from a full interview, which is linked but both the site and the link are dead. And the grandparent's only comments on the account are in this thread, supplying the "sources." Here's a 2013 non-HN thread accusing him of smurfing accounts for publicity [0].

2. His publicity and claims seem intentionally difficult to prove.[1] (Note: another low-credibility source.)

3. His LinkedIn profile lists 99th percentile standardized test scores (LSAT and GRE). Normally, this isn't notable, but my "BS" pattern-matching is flagging this within the context of #1 and #2.
