They have an app which is ad supported, and they are trying to become of a social network like reddit by requiring you to login for more features, and adding upvotes and other interactivity.
AFAIK both of these are using methods that are either deemed acceptable by adblockers (like how Google was using plain blue/black text instead of stroboscopic gif banners), and/or adblockers have trouble with them because they come from the same source ?
