Gregory's Server@david_chisnall i like to make a distinction between advertising and direct marketing. web “ads” are almost all direct marketing
another problem with web “ads” is how appallingly wasteful they are, running so much code in the browser and doing a real time auction (!!!) content-based ads can be chosen ahead of time so there’s no need for client side code and most server-side processing can be amortised
@fanf @david_chisnall I think you hit the nail on the head that profile-based ads are direct marketing. Should be subject to the same legal framework — ie must establish user consent first.
