This data is not public (yet) but it will be soon, it's not based on Cloudflare data. I'm not the only one who has observed it either; there are reasons why both attack mitigation solution providers and end-networks filter and/or block Tor.

So, what percentage of the volume/outflow from those same proxies was "non-malicious"?

Surely you're making the mistake of categorizing the neighborhood, when you should be categorizing the people?

By comparison: what percentage of the world's SMTP is spam? What percentage of the world's HTTP is filesharing?

If you're not looking at the whole picture, you are making a "one bad apple" mistake - amplified, because Tor rotates their occasional bad apples around exit nodes just like everyone else.
