I have paid web site hosting from the company doteasy.com. On their default 404 pages for when a document is not found on my web site, they place advertisements for their hosting service. I’ve used a lot of different web site hosts before and I’ve never seen such insidious advertisemtns from a pay host. This is the sort of thing that I’d expect from the likes of geocities, not from a company that I’m paying more than a hundred dollars a year!
