Do not find excuses (and vague statements or technical bulls) and learn, you don't know what you are talking about and don't get the global picture, we don't care about the Tor network and they don't care about others neither do they care that they increase their network, so indeed let's stop this discussion Just replying here (for the last time) because expecting more clever thoughts about what I wrote, maybe one day... but for sure something like this will happen in the future Le 09/11/2019 à 21:21, LORD HIS EXCELLENCY JAMES HRMH a écrit : > We do not need to discuss this back and forward publickly.
