Now not only have I been using a blocker for a few years, I install one on any family/friends computers I am working on, and advocate for one whenever it comes up.
I don't know what it would take for me to come back now. Unfortunately it's a tragedy of the commons: a small number of sites/advertisers can completely ruin it for everyone -- and, I'd argue, already have.
Taboola and Outbrain at least have manual reviewers attempting to uphold a certain standard for content, though there is a ton of room for improvement. I've never noticed a lot of suspect traffic coming from these two, which is in stark contrast to networks like content.ad or adblade. Of course, Outbrain/Taboola don't compare to the big networks, but I've experienced a good balance of affordable and reasonable quality traffic, though this isn't always the case, as costs/quality can be quite variable over time.
