"At times, banning a person may not be entirely effective. With the design of browsers, it's easy for a problematic user to register a new account. Discouraging aims to make using the site slow and painful for a problematic user, such that they eventually give up and leave."
Yeah this is a forced thing.
Try pinging 172.19.0.11 (tunneling IP) and 54.36.126.11 and see what is says using cmd.
Again, pretty sure that the truth is that your incoming traffic has been blocked by a high ranking member of staff due to something you have done.
The tunneling IP will most likely time out anyway as it is a traffic tunnel (sort of proxy/fake ip/i cant explain it too drunk)
Other than this, what ISP do you have and what router are you using?
