list policy re patent discussion

My understanding of the policy of this list is that we do not discuss 
patents in this forum.

PROPOSAL:
Please can we strengthen that policy to any discussion of patents is
a) excised from the archive
and
b) the list chair is empowered to block offenders who are either:
- persistent
- or appear to be solely publicizing their claims rather than making a 
misguided effort to participate in discussion


(Maybe (b) should be modified to have a yellow card and a red card!)
