Ads, especially adsense by Google, are the major source of revenue for many web sites including ISC.
The ads are tuned in such a way as to link to the keywords occurring in our online contents. Especially when we are approved for adsense or other ad affiliation, the ads are shown in our pages as per our choice and pre-determined way.
In ISC there are some safety measures to avoid mistaken clicks on ads by the adsense members themselves on their pos and pages, when they are logged in.
Otherwise the ads are freely seen being shown on the content pages.
Earlier the ad block software were blocking the ads , but even they do not block all ads. As many free sites exist on the ad revenues, the ad blocking is not encouraged. You can use ad blocking software if you feel the ads are quite nuisance, otherwise we can just bear them. Sometimes the ads help us to know what is there latest and may even be useful to us.
However as I am using desktop and mostly not the first to respond, probably I am not seeing them hiding my post/profile. Hope the WMs may evaluate the issue and come with a solution.
