I don't care much about bridge or non-bridge adds, as long as I'm not bothered with them! This means: NO POPUPS, NO PERSONAL MESSAGES!!! Banner ok with me, put a hot girl in bikini on it and we'll all love it

But from the moment I need to click something to get the advertisement away, I'm against it!
As to Deanrover's questions:
i) I'm already annoyed with all the personal messages I get when I haven't been online for 2 days. Give me some extra popups or messages with adds I'm not interested in and I throw my XP through the windows

You know what I mean... Would I use BBO less? Perhaps. Would I leave BBO? Not in the near future, but if the adds are sprayed to us, then I'd go for sure!
ii) Paying for an ad-free BBO? No way... I hate to pay for stuff on computers, since you can get most things for free

I think I'd try to manage a way to get rid of the adds. As I told in i), when it would become too annoying, I might leave, but I won't pay.
