Google isn't saying it that content can't exist in an app - they're saying the app doesn't have a sufficient level of moderation for dealing with issues that do occur.

What’s a sufficient level of moderation? I’m seriously asking. Would love to see some self reported and also verifiable stats from all the platforms being discussed here.

Any moderation would be a start. Gab's whole raison d'etre is to be an unmoderated social network where you can post the hate speech which would get you kicked off more mainstream networks.

I'd also like to see verifiable stats.

Anecdotally, when I tried Gab, the ratio of violent racist content to normal content was way way higher than on other platforms (even if the absolute amount is much higher on twitter due to popularity, the ratio is lower).

You won't be able to find speech inciting credible threats of unconditional violence against specific individuals that won't be taken down after being reported, no. "Racist speech" doesn't necessarily meet the bar.

> So I won't be able to find hate speech, racist speech, and speech inciting violence on Facebook and Twitter?

You'll be able to report it, and have a reasonable chance of action being taken on it.
