Giovanni,
For me, Commercials using this technique are cannon fodder to be blocked.

I tried to write something similar in the past
(https://github.com/apache/spamassassin/blob/trunk/rulesrc/sandbox/gbechis/20_html.cf)
but I disabled them
since they hit lot of commercial newsletters as well.
We can write a rule and I can add it to my sandbox for testing, could you share
(privately if you prefer) a spam email using this technique ?
Thanks
Giovanni
