You assume Google will remain relevant in adult. That may not be the case for much longer. They have already dropped adult adwords, censored adult content on major keywords and made moves toward 'sterilizing' their results.
An engine for adult may be just in time, and the data you are talking about is not that hard to get from adult-specific sources if they make some smart moves.
