More-pertinently, I wonder how many of the developers of reddit's new ad system themselves have ad blockers installed. Do any of them actually see the results of their work?
Reddit ads were what finally pushed me into install ublock origin about a year ago (redditor since 2007).
They had a misbehaving ad (downloaded a ton of "stuff" over and over and over). I reported it on one of the their support subreddits and was told "don't recognize the add urls. scan your system for a virus". It was a pretty good error report too (screen shots, console log, etc).
Installed ublock origin that day and haven't looked back.
FWIW, when I worked at reddit, I never ran an ad blocker. In fact, I didn't run one for about five years after, until my CPU started spiking on just about every web page I visited.
But even then, I whitelisted reddit.
So my guess is yes, they see the output of their work.
