The Bing ad comes from Google Ads. We have the option to reject any ad they send us, and will be doing so here. Howie is on a boat, and will be dealing with this when he gets to a PC.
Let's face it: it's a fine line we tread. If ads become too obtrusive we lose users. If an advertiser is not a good fit for us (pissing everyone off), then their advertising is counter productive for everyone. In 2003(4?) we had a rather lively discussion about a rather large shark that had been killed in a tournament. The Google ads for shark fins simply did not have a place in that discussion or elsewhere on our board. We banned them from the site.
Anyone who knows me, knows I am not a greedy person... in fact many of them wished I was a bit more profit driven than I am. The domain ScubaBoard has been entrusted to me largely due to this philosophy of mine and I refuse to let money be the rudder that steers this ship.
