That would be construed as intentional jamming, I was speculating
about the impact of inadvertent (unintentional) rfi.

I was thinking that the unintented noisy consequence from the 
inadvertent rfi might cause a Ham to stop sending unidentified 
transmissions into a repeater -- it was not a suggestion that
anyone jam a *legal* user (WalMart).

This is radically different than BPL where the promoters are
knowingly lying about the destructive impact of a secondary user
(BPL) upon primary users -- there one may freely operate normal
modes and power levels without concern for the BPL system --
they (BPL vendors) are required to defend their gear from
*legal primary users* including Amateur Radio, government
and military users, etc.

This does not mean pointing large beams at BPL devices and
pumping a KW of digital RF into the beam -- in that case
one is not operating for the purpose of communicating with
another Op.  One is also supposed to only use the power level
necessary for successful communication, not the maximum
legal just because one owns an amp.
