Uh, yeah, it kinda is. Maybe not over here, but different places have different policies.
It's not a policy thing. It's a logical thing about how messageboard software works. It doesn't make sense. "Banned with a tool that doesn't work very well" as opposed to "banned with a tool that works a bit better". It just means you're banned more effectively. It doesn't mean you're "more banned".
Being in a jail cell with 3 guards outside isn't a "greater" imprisonment that being in one with just one guard outside. It just works better.
