1) Tackling abuse requires a consistent definition of abuse that transcends cultures and can be implemented without major privacy and&#x2F;or censorship implications.<p>2) The fact I can avoid the large networks and mitigates the abuse problems simultaneously implies the issue is largely a values issue rather than a technical one about how one defines abuse.<p>3) 99.9999999% of the spam I have to mitigate comes from &quot;big networks&quot;. I&#x27;ve literally had 1 piece of spam in 2016 come from Tor. I&#x27;ve only ever had DoS&#x2F;DDoS from compromised servers on &quot;big networks&quot; who fail to notice for day(s) and require manual notification. So when you say &quot;abuse problems&quot;, it clearly means something different to you than it does to me.<p>4) The &quot;big networks&quot; are not interested in cooperating with relatively cheap solutions like the one CF is now implementing until they are publicly called out. I asked for that 4+ years ago and was ready to move an account at $DayJob to CF until I realized how unresponsive they were.
