SO apparently, they won't let me go into their Discord server, so I got an error message that's saying "Whoops... Unable to accept invite". Why was that?

Might be because my IP was banned, that's why.

Got the same problem, they called me troll because they can't believe that "net price" is a price without taxes and billion could have 9 or 12 zeroes. Maybe it's time to warn them that we can suspend their server because of inappropriate reason of ban?
