[SpamCop-List] ISP suggests own network be RBL'd?

[Chris Abbey]

I just got a response to an month old lart that was simply:

Please report this spam to MAPS RBL.

This was from someone on the network of origin. Is he seriously
suggesting that I should propose a RBL of his own network??

the relevant headers for the original spam were:

and this one which was discarded as fake

the response came from @interq.or.jp.

I'm suspecting either an incomplete understanding of RBL, or
a shaky grasp on english ... or I'm really out of it today and
missing something entirely.
