Do you have a court case backing that statement? If not, then I think
you're playing a bit too much of the lawyer for a public mailing list.

Again, it's not at all clear that such a claim would stand up in court
and threatening to kick people off of public mailing lists for talking
about patents is patently ridiculous. You could make a similar claim
that we should go through our mail archive and remove any post that ever
talked about a patent in case we're required to provide web access logs
that show someone looked at a page that talked about a patent.

And all of that without even bringing up the fact that core folks have
talked about patents on this list in the past.

Thanks,
