> That's just not how digital ad campaigns are run. At that point I'd expect sites like Stack Overflow to point out that they have a specific of way of running their sites as well - and that shouldn't include having ads execute arbitary javascript. While those requirements would certainly exclude a significant number of ad agencies, I can't imagine that there aren't enough advertisers left that would happily play by Stack Overflow's rules to reach a rather large and specific target audience with (likely) disposable income.
