Whenever I see a whiney little message pop up about me using an ad blocker on a website, I never go back.
Especially when I'm *not* using an ad-blocker. I'm blocking third-party cookies and the like. Although I suppose that means I'm using a TARGETED-ad blocker, so the words fit in there someplace.
Recently I went to an Amazon listing for a product I had looked at, and had even put on my "wish list" to pick up at a later date. Ads for that specific listing started showing up everywhere, so I put a "product review" on the product that I would NOT be buying it specifically because the ads were harassing me.
Maybe we ALL need to start flooding product reviews with such statements. Maybe even make an add-in for Firefox & others that will automate it for us.
