I would like to point out that it is not just ICB members who read this site. There are inmumerous 'guests'. These people can be anyone and may include big industry players, retail managers, consumer survery groups, potential homebrew supply retailers, goat herders, those in other countries and members of other beer sites, and anyone else whos happy to stay anonymous while keeping tabs on ICBs level of knowledge, and in its progress and development as a site.
So the complaint may have been made by anyone, member or otherwise. A site like this one strikes me as "Resource No. 1" for anyone with a commercial interest in beer or brewing in Ireland. On this site a debate raged about possible false advertising. Somone followed this debate (I have no doubt that the complaint stemmed from this site) and decided that they wanted to complain, for whatever reason they can justify to themselves. Could have been anyone. Could've been me, could've been Arthur Guinness himself, back from the dead.
This is an important point for everyone to remember.
