I'm staying in the middle on this one. While I think that 1 week is a little extreme, like said, he didn't learn. You should really just listen more guy, so a fat PERM doesn't head your way. If you want people to see things do it outside the server, even if you think that it's a stupid rule or that "oh they won't really do anything about it", that's the wrong mindset.
The only reason for a week ban is its not based on what you did, it's the trouble you have caused beforehand.
The commbands have been less frequent recently, so I think he is learning, hopefully nothing else will come up after this
