Adblock?

Do you own a site and if yes, do you deal with adblock? I saw some sites preventing readers from proceeding until they turn off their adblock and personally, I dislike such sites because my adblock is turned on by default. I only turn off adblock for sites which I really enjoy and want to support it. For me to know if the site is worth turning off adblock, I will first need to see the content beforehand. On my blog, I do not use such system to force readers to turn off adblock because I want to ensure a better user experience. What about you?
