anti-adblock javascript, weak?

[sbk]

I don't know javascript so don't know if this actually works, but maybe this is interesting. Multiple posts dealing with counter-acting Adblock hidden-technology.blogspot. Notice they are dated 2008.

Using javascript ("client side", user's PC) seems vulnerable to client-side counter-counter-defense. But in the end, the client can always block something...

This looks sneaky. It has a timer, so I guess it sniffs and records user's text selections. Spying on behavior.

Years ago, when many on the internet cheered AJAX, I already wondered how to block AJAX. I assume ECMAScript references list certain AJAX functions?

Also, quick Wikipedia: [ul=https://en.wikipedia.org/wiki/JSON#Use_in_Ajax]AJAX is part of JSON[/url]
