I've been wondering when someone would start complaining about wanadoo.
I have been reporting two or three ftp scans a day for months! Let's
hope that they actually do something about it now.

Not far behind wanadoo.fr is t-online.de (which I believe is a large
German ISP). I am seeing about five ftp scans a week from t-online.de,
all are reported to their abuse address.

Does anyone have any contacts who might ba able to get some real action
on this issue?

Cheers, Russell
