This could be construed as bringing BA into disrepute, if the author was an employee, no?
Hi there - no, the use of metatags would be no grounds for BA taking any interest.
All you do is add keywords to the sites HTML - there would be no cause nor justification for BA to take action against anyone for doing that as the source code is not 'published' per se.
If the chap had set up a site with links that may be something different - as I understand it he simply set up a re-direct to a porn site. It wasn't even a fake site - simply a re-direct.
