Whoa. I missed this one.

I used Meetup for years to power the "Tech Events Network" with 50+ US city-based accounts like https://twitter.com/ATXTechEvents

Over the ~5 years I ran it, it was up to 4M+ impressions/month with a massive newsletter and pushing tons of traffic to tech groups, mostly hosted on Meetup. Then Meetup changed their API policy and said this was "an inappropriate use of the API" and poof, gone.

Frustrating as hell because group leaders loved it and most of the traffic was going to them anyway. Arg.
