is there any change on site?
everything was fine .. but since yesterday keep getting message to turn off adblock (which i dont use)... tried on several clean browsers (no plugins and add ons) and get same message...
Sometimes I get this message when I just start up my computer/my browser as well. Ultimately check if you do see any ads?
If the ads don't load (for whatever reason) then the anti-ad detection will kick in.
iirc, the adblock message pops up when there is a longer gap between the time your browser sends a ping to the website/server and the time it takes to serve the page. Usually, when you first open your browser, there are either many pages that need to open from your last session, or your browser is still configuring itself to use, so you'll see a small pause when you try to open a website.
If you are also downloading something to your computer, or are on a slow internet connection, you will see the adblock message. This happens to me occasionally on several sites, as I'm on a slow connection. I just simply refresh, and the problem fixes itself.
