Admins are aware of what is going on with jumpy ads - there is testing happening - and we’re working on it with the developers.
Update 5/2: We have killed the ads while I work with the developers to improve site performance. If you are still seeing them, do a hard refresh or clear cookies.
Update 5/3: THEY ARE BACK I LOVE THIS MY FAVORITE. I am working with the ad network developers in some strong words. Please post any and all screenshots of brokenness if you can on this thread.
Update 5/5: We are still having issues with ads, but a number of problems are fixed. Unfortunately, blocking ad for patrons is not still funcitonal. Screenshots are still helpful.
