"Spam" and "Threads" have no meaning to me except as a can of food or thread for a needle. You do have a technical problem if it does not belong on this site as a sanctioned ad.Moderators cannot do anything about spam threads unless they know about those threads. When you see spam, use the "Report" function to alert moderators. We are not mind-readers!
The Report button/function is accessed by clicking the three dots on the right side of every message and then choosing "Report".
As far as I can tell, what was posted was a thread, not an "ad" per se. If you see a spam thread, report it using the "Report" function.
This is why I do not use google search or bing, I use DuckDuckGoAds don't work like that. Every one sees different ads. Google customizes them based on your browsing history. Some are in common, as in the bee related ones because Google knows this is a bee site.
Try this for a week:
Google dog food. Go to dog food sites. Go to dog forums.
Google Depends. Look up incontinence on WebMD.
Now check out your ads.
Have some fun:
Get on your friends computer and search for sex toys and lingerie every time they leave their desk
Google allows a site to block certain ads, but if the mods cant see the ad you are seeing they can't notify google. We asked for it and now its here.
This is how the current IT consumer industry works as a whole - in case someone still did not notice.Notifications, tokens, whatever, are all designed to keep you active on the site which means your see more and, which means more revenue.
