Well, here is one point I was too timid to raise on Thursday with 5 minutes left. If services providers are pushing a range of adverts most of which are simple gifs with an alt text. Then how can the site using the advertising know for certain that there are not one or two inaccessible ads and hence ruining their conformance. I have been thinking about it, and since most sites use <iframe> to have ad content served up to their site. This means that all the things we are asking them to stop ad content from doing they have no control over. This brings us full circle to that the ad content providers have to comply. I am also afraid, however trivial it seems this is an issue we have to deal with thoroughly we can not sweep it under the carpet. The reason I say this is that whatever our own thoughts on the matter WCAG is quickly becoming the defacto standard of what reasonable levels of accessibility. I can see a situation where someone finds a site inaccessible, sues the site, who sue the ad provider. This of course would lead to a whole lot of wrangling over what is accessible and what isn't, and WCAG being used to justify two cases at once. Whatever legal decision happened could easily put acceptable accessibility in a direction we do not agree with. So as political as it is, I suggest that we make sure whatever our line is on this is rock solid. This I don't think is. So I guess I have to fall back on what Cynthia said, this is something EO should look at. If they can get conformance (not really a hard thing) from the ad providers there will be much less of problem.

The suggestion was that sites be allowed to claim conformance even if advertisements did not conform as long as the advertisements did not block access to the rest of the content. Ways that ads could block access to the rest of the content included: 1. causing seizures 2. distraction 3. flashing screen reader readable text which might grab focus of screen readers 4. pop ups 5. advertisements which either steal or keep keyboard focus 6. ads which make a page refresh periodically and thus caused screen readers to reset. It was commented that all but the seizure part might be okay if it was only temporary. That is, it only continued for a short period of time and then stopped automatically - or - if it was easy for the user to stop it. That is, the behavior only persists for N seconds after the person first enters the page (where N is two or three seconds or so but probably not as long as 8 or 10). It was also felt that if the user agent could prevent or turn off any of these behaviors then there would not be a need for the author to do that. It would still be recommended that the authors not do it, but it wouldn't be a requirement. The definition of distraction has to be crafted very carefully since static bright letters might be distracting. In this case it really means distraction via movement etc. It was also pointed out that the purpose of advertisements is to distract.
