Here's our source's story about being banned from Facebook: Our first product went live last year and we executed our strategy well - we self managed our Facebook mobile app install campaign and got a very nice ROI.
Usage continued to grow week after week, we reached the #1 spot in the app store when searching for the particular vertical we went after, got tons of 5 star reviews, and all was well.
When I pressed further about what an approved advertiser was or how I could become one, the only answer I got, from multiple representatives, was that it's just a company with a prior relationship with Facebook, and that they're not currently accept any new approved advertisers at this time. We've tried getting info from friends who work at Facebook, prior representatives we've worked with (we've been advertising on Facebook since 2010 in previous non-dating sites we've built), only to receive the same boilerplate response about approved advertisers.
We even tried going through a large intermediary which specializes in mobile ad campaigns, and they were equally surprised to learn about this moratorium.
Revenue was over $1k / day at our peak, and we were profitable.
