Very difficult.... we had a similar problem. One bad customer and SPEWS
blackholes not only our corporate LAN but also my HOME address range,
and that of my home ISP, who was not even peripherally involved.

We just had to sit it out, as SPEWS is not accountable, or contactable.
Eventually the listing decayed, but it was a real problem for us while
it lasted.

Since SPEWS, with its complete lack of accountability, started being
used by respectable spam blocking software. Yes, its a massive problem.
