"The people you were targeting undoubtedly would have been in that frame of mind where they weren't going to think straight. You were relying on the fact they were going to panic and pay the money."
Even though homosexuality was decriminalised quite a long time ago, many gay men (and women) are still reluctant to 'own' who they are, so leaving themselves open to this kind of nonsense. To some extent this is understandable because however 'right on' we may like to kid oursleves that Britain is today, there are still a lot of prejudiced people around who don't hesitate to make life difficult for gay people if they think they can get away with it (just remind yourself how successful a number of major religions are in having their prejudices accepted and in a number of cases enshrined in law). Whilst this is in some respects a depressingly familiar type of case, at least it has a 'happy' outcome - the culptrit has been brought to book.
