I use various ad blocks, some of which come with my browser. My purpose in using them is to block pop-up ads, block questionable ads, and hopefully eliminate some tracking. However, when I see a site that has notified me that they have detected adblocking, and I actually think that I can trust the site, I will disable the AdBlock for that site. Of course, If the site doesn't seem like one I could trust, or I have no intention of returning, I will leave AdBlock in place and never venture to that website again. I am for supporting the websites I visit on a regular basis either by allowing them to show me ads, or on rare occasions (infrequent) subscribing to their content.
