We can we also tell this to every politician (and their idiot cronies/cults), religion, insurance company, and car dealership? I hate their ads all over television, billboards, phone, internet, etc... Well, I quite like the Subaru ads... To do so just drop network TV, even better, I do not have one book in my house that has ads in the middle, not one blu-ray that interrupts the move with ads, not one song on my iPod that stops every little bit to play an ad. Netflix's doesn't interrupt my move with ads. Lots of choices beyond the sit there and shovel it too me method of entertainment.
Phone - caller ID. I don't know you, I don't answer.
Billboards - pay attention to your driving, not your cell phone, the person sitting next to you, the shops along the way or the billboards.
Internet-If you haven't figure that one out, unplug your computer or quite going to those porn sites. They you won't get all that unsolicited SPAM.
What I find funny, is that it's not bad manners. If you're using Facebook, you have to realize there will be ads on there. That's part of Facebook. Facebook connects you to things... some things are friends, some things are events, and others are businesses. You also have to realize if you are using Facebook there are a lot of people that don't like the unsolicited ads and choose to object.. That's part of Facebook.
If you don't want ads on Facebook, then... don't use Facebook? If you don't want people commenting on you unsolicited spam, then... don't use Facebook.
To me, bad manners means an impoliteness resulting from an ignorance of an accepted social norm (thanks internet!

). For example, using a free social media site (say, Facebook) with full-knowledge of a particular pitfall (say, people detesting spam and the spammers) and then go on to complain about said pitfall the backlash to their spam causes. It's a free service; they have to make money somehow. You knew it when you signed up for their free service and chose to be a part of the problem by adding your spam to the rest that not everyone would like it.
(As a side note, if you're PAYING for a service, and you send unsolicited ads, well then you absolutely have no right to complain, IMO.
