I’m surprised nobody’s done this by now.

If you hate that ad, here’s the contact information to the guy who thought it was a good idea to do:

Info:

Managing Director:

Henry Motteram
mob: 0414 449 852

Go also to their facebook page and report the links as offensive (you’ll have to choose the flag button, then use one of the reasons they give you (the closest of which is for discrimination against disease or disability).   And while your at it, go also to their other facebook page (for the ad itself), and flag it too.

This is an advertising agency.  They’ll understand that if you make too many people pissed off, you won’t get the business you are looking for (especially when said people discuss things like “boycotting the people you are advertising for if you don’t take down the offensive ad, and facebook pages”).
