Oh, I see. Yes, that's correct. There are all kinds of DOS
attacks against any public Internet service. The ones to worry about
are the ones that let a single user with a slow Internet connection
deny service to a large number of people. The ones that require being
singled out for destruction by large ISPs, there's nothing that can
really be done about.
