Why use TOR at the first place anyway? Can't you use normally? I never used TOR. So I never faced anything like that. Sometimes I would get random time outs or verification failed but not that you got.
Some people on this forum prefer to remain anonymous, such people will prefer to use Tor which is better in masking someone's identify than any other means. Some people use VPN also (paid VPN). VPN is private and centralized unlike Tor which is not centralized like VPN.
Right, one side is privacy. We are at a bitcoin forum where financial matters are discussed and thus anonymity is tightly tied with security.
Another side is that in some countries this forum is banned by authorities and it is impossible to visit it without Tor or VPN. So some of us need to use something of that just to be able to get here.
