Public Service Announcements are often aired either when someone hasn't paid for an ad for that spot, they want to be able to say they are serving the public (since the airwaves are theoretically public, broadcast stations have to theoretically serve the public good), or someone actually did pay for them Anyway, in other articles similar to this that were in the USA (where the law about not having to pay for unsolicited packages applies) the people were getting several packages every day (If I recall it was dozens). So getting one or two things you didn't ask for would be fun, getting several of them every day would not.
