kpnqwest.at for example ;-) t-online.de is another one, they take
something like that pretty serious in the meantime.

Often it does, complaining as <abuse@kpnqwest.at> has sometimes more
weight in $otherisps eyes than as <waldner@waldner.priv.at>, not only
because we´re a fellow isp but also because another pair of eyes
(which should have some clue at least) scanned the complaint for
sanity.

In the non-profit environment they may not be so eager because (I
guess) you don´t give them any money at all, but for most isps, this
matters (not alot with a simple dialup-customer, but bad publicity
would also hit).

This happened a few times, dropping a peering often helps because the
other isp has to pay for more upstream...and it´s not only a matter of
law but also of good business relationships and morale.

They are also the first to be expected to do something, but you only
have a single point of view, your isp has a much broader base.
