First of all, it's your responsibility to make sure your website functions properly, not mine. Secondly, while I have Adblock installed it isn't causing the problem, and in fact my primary query is the reason I use it on your site.

I have been having problems, at least I consider them problems, with ads on DA redirecting me without warning. The most recent time this occurred, I took a screenshot ([link]). Frankly, you need to vet your advertisers better.
