Again, if your harassment is legitimate, then you could continue the fight instead of giving up. Just one person against a billionaire, yes. That would be quite an uphill battle. But a few hundred, a thousand, a million? That number starts to make ripples.
It seems to me, the prime issue is the spread of misinformation. It is not Zuckerberg you have to contend with but rather the U.S. Government. Apparently, they gave Google and Facebook notice that they're unhappy with their spread of misinformation.
If your information is not factual, and can't be verified, then there is nothing nefarious going on here and you're simply a victim. Not a victim of billionaires but of propaganda.
