What should happen for 'tracker' images? (i.e. <img

As some examples, Geocities has alt="setstats", someone has
alt="statystyka", someone has alt="CrawlTrack: free crawlers and
spiders tracking script for webmaster- SEO script -script gratuit de
détection des robots pour webmaster", etc, and those examples do not
help users who are seeing the alt text.
Such images are pretty common, and they're not going to go away, so we
should minimise their harm by saying alt="" is appropriate. None of
the cases in the spec seem to cover this case yet.
Moreover, such images often use width=0 height=0, but that's invalid per
HTML5, which seems a bit unhelpful.
google.com is splitting the image up to fit it in a layout table,
which is non-conforming HTML5; but there are other more legitimate
reasons for having several img elements representing a single piece of
text, and in those cases it seems sensible to put alt="all the text"
on one image and alt="" on the others. Should HTML5 be changed to
accept this?
For instance it would be reasonable to use two images -- a filled star and
an unfilled star -- to represent a rating of something:
<p>Rating: <img src=1><img src=1><img src=1><img src=0><img src=0></p>
You'd want the text version to be:
Rating: 3/5
Hence:
<p>Rating: <img src=1 alt=3/5><img src=1 alt><img src=1 alt><img
src=0 alt><img src=0 alt></p>
