I wonder how many people are experiencing this and never say anything, or just go away...
Based on statistical data with the daily traffic and number of posts on the site... not that many people.
If I am supposed to know which ad that is based on your screenshot. I have no idea. As previously stated, there are more than 150,000 possible Google ads that appear on scubaboard. Each google ad is customized for an individual user by Google.
If you're getting ads you don't like, you can do one of several things.
1) You can clear your cookies, and you'll get different ads.
2) You can click on the little blue thing that looks like a line arrow (the Ad Choices) icon at the top right of any google ad, and tell them you don't like that ad, and then you won't see it anymore.
3) You can become a supporting member, support this site directly, and shut off the Google Ads.
If anyone else wants to provide specific links to URL's of offending ads, I can do something. Otherwise, there's nothing else for me to do.
Thanks.
