interesting choice of words.  i was under the impression that these were advertisements, not spam.  and, as has been pointed out, they can be turned off in your forum settings.

i have no banners, nor am i ever likely to - but honestly, i find the increasing use of them to be indicative of the health of Bitcoin.  the more of them there are - presumably mostly paid for in some way - the more satisfied i am with Bitcoin's adoption and eventual acceptance into the mainstream.

surely you couldn't object to that?
