Ronan Mullen says that he originally told the story in an interview to illustrate the prevailing culture in the Oireachtas and this is the culture that we all want stamped out.
I suspect that the reason that he wont name names is that it was a friend that said it and he doesnt want to embarrass him/her.
Stamping out this culture means going after all offenders to ensure that the rest of them get a fright.
In the case of TDs, we can all do our bit by making sure that we vote accordingly and let every candidate know that we will be doing that.
Of course, the Seanad is different as they are not voted by the people, but by some arcane bizarre undemocratic system, so they feel safer from being voted out by the riff-raff.
