Shift’s ban system doesn’t ban IP addresses. It bans username and email. Thus you being able to still get on with your phone. If Shift banned by IP address, both your streetsweeper account and timmasterde account wouldn’t have been able to be created or even view the forum.
Response to your edit: So essentially you made this thread to make people believe the timmasterde was you, but it wasn’t? Interesting. I’ll make note of that.
