If HR passed on them because 'porn' they either abused their position or gave a clear signal about company culture. They need to find someone that fits. In terms of skills and team fit/professionalism.

Either the company values prude/neoconservative value signaling (the at least I wouldn't want to work there and they should openly tell people what ideology is expected) or the HR person abused their position and did not do their job in finding someone that fits the skill set and role.

Either way is hypocritical in my book.
