I haven’t heard of these before.
In general though, it’s fair to say we all stand to benefit from a better-regulated environment. There comes a point, though, where things get a little silly. I’m not calling into question IGASA’s good intentions here, but their codes of conduct do appear to merely reflect what good advertisers are already doing.
Their Code of Conduct (http://igasa.org/codeofconduct.php) warns against the use of spyware, click fraud, code skimming, hateful site content, or plain unlawfulness. They are – fairly oddly – also keen to prevent ‘Content offering genuine or replica guns, bombs, ammunition or other offensive weapons for sale.’
If you are an advertiser or publisher worth your salt, you don’t really need to join an association to realise that any of these dodgy activities won’t get you anywhere. If you want your internet advertising to be profitable, you need to be fair and honest from the word “go”, otherwise things are likely to backfire for you.
