> From our parent: I used to work in the antivirus industry, and, as I recall, anything that even hinted at a history of hacking or virus-writing would lead to instant dismissal and black-listing (from pretty much the entire computer security industry).

A number of notable, convicted hackers have done additional work (whether employment or successful entrepreneurship or both) in the computer industry (in security-related or other subfields) after conviction. Kevin Mitnick, Julian Assange -- long before WikiLeaks -- and YC's cofounder Robert Tappan Morris are among the more notable examples.
