2. Cloudflare... why do mixers keep using a US based MITM? This is terrible for privacy and makes me wonder they only care about not getting DDoS'ed for the case of getting more customers and money, WHILE NOT PROTECTING THEIR PRIVACY, which is the MOST IMPORTANT PART!
3. More info should be available in the mixing page. Where the coins are going to and time of the mixing. You can only see that in the letter of guarantee.
I can't comment on what they do with the coins and what happens in the back-end, because I have no access to it. Do they mix your coins and send you "clean coins from exchanges"? They may, they may not. There isn't much to say about it.
1. Wording on Free Mix Active updated again.
2. TOR connection is available, also CloudFlare allows server inside network secure to accept external connections with no port forward and no opening firewall with special Argo service.
3. You are right, most of that info is on the other pages but on the mixing page you have to rely on the letter but you suppose by then you are already informed? I will see if I can make it print "This address is valid for 168 hours from 2020-08-12 12:48:36 GMT" in an update. It would be good a little technical.
