I attempted to log in today and came across a prompt saying my IP was banned. After a bit of confusion and wondering whom I might have pissed off, I noticed that I was still in vpn mode. When my vpn isn’t active, I can access the site just fine. I’m a noob around this issue. It appears it is discernible for a site to know if one is connecting through a vpn or not, why is there a restriction for doing so? Also, does this mean when I’m on a vpn, elitetrader forum is off-limits and that there is no setting to adjust like a whitelist or something?
