Well, perhaps not. PF does not accept this use case as valid, neither
did the WAI Ad Hoc that provided guidance on alt three years ago, nor
has the TF agreed this use case is valid.

Quoting from Ted's CP:

"The spec currently allows conformance checkers to waive alt=""
conformance requirements on pages with <meta name=generator> present.
This feature is intended to allow sites like Flickr (which accept bulk
photo uploads from their users and can't reasonably require their users
to provide alternative text) to check the conformance of their Web
applications without being inundated with warnings or errors that the
site developers can't do anything about. If we don't allow such sites to
do this, they have and will add bogus alt="" text to their pages simply
to pass in popular conformance checkers, thus harming the accessibility
of their pages."

This paragraph contains three false assertions:

1.)	The 2009 guidance document from the WAI Ad Hoc provided a solution that
that site developers could adopt which would satisfy alt concerns when
individual authors failed to provide individualized alt text.

The assertion that large site developers are hapless victims is false.
Repeating this false assertion will not make it true.

2.)	It is asserted that developers would fill alt with bogus text.
But, no evidence has yet been provided in support of this claim. This
assertion is also false, and repeating it will also not make it true.

3.)	If bogus text were inserted, it is asserted this would cause
harm to a11y? But, what harm? This has never been demonstrated and is,
in fact, also a false assertion whose repetition will not make it true.

This use case is a bogus, red herring.
