This phenomenon has consumed every social media outlet, especially Facebook and Twitter. It's gotten to such a point that they don't even try to hide it anymore, while they collect and sell user data as well. YouTube recently got a major heap of shit for taking down politically-oriented videos while allowing "kid-friendly" videos with abuse and child sexualization (pro-pedophilia) to accumulate hundreds of millions of views, and in some cases, double digit billions.
You shouldn't be surprised that your anti-Zionism content is targeted, though.
