I don't really see how its a burden on anyone. I just like to browse 2+2 for one hour a week, I don't really post. Just convenient for me so I don't have to delete the cookies and asked to be unbanned and then banned again the next week.
I request self-control instead. While this might not really be a burden on anyone, I don't want people to start screwing around with these requests. I'm not saying you're doing that, but weekly bans like this aren't really what the system is there for.
