it's not either/or - you can object to this and page 3.
the alternative to supposedly 'playing into the advertisers' hands' by objecting to this is pretending it doesn't happen and allowing it to continue unchecked. Personally I think that would be playing into the advertisers' hands far more effectively - it won't go away if we ignore it, there will just be more and more of the same as other companies copy and it becomes established as a normal thing to do.
Hadn't seen that, seth. I would have thought that if you make the point to the ASA that the posters are public - ie displayed in shop windows facing out into the street/shopping centre - they may accept it. They accept complaints about internet material too.
I take your point about complaining to the company itself.
