No one here mentioned the likely reason that the ads were blocked by the ad review system (a combination of ML and people in India or something). I don't know exactly how it works, but I'm pretty sure it is risky for Facebook to allow ads to run with trademarks that the advertiser does not own.
The Google+ logo is a trademark.
Can he try running an ad with just his face? It still might get disabled (in which case it probably is for competitive reasons) but I suspect that would take a lot longer... Especially if he doesn't say Google+.
"I have moved to another social network. Click here to find me now" would likely get past filters.
A million times this. I bet, with their volume, very few ads would make it to the human-review stage at Facebook. This was most likely caught by an automated filter that didn't like something (e.g., the trademark image) about the ad.
Never attribute to malice what can easily be attributed to stupidity, or in this case, naive artificial intelligence.
