If it's in the rules, don't do it - cannot be much clearer then that.
You could have used the .tag function? Just like the pug the other day, I didn't pick "sh" as I didn't know who that was, later found out it was you nicklaming once again and so the teams were very unbalanced.
Deserved ban from my perspective, it just ruins the picking order of the pug. You were simply asking for the ban there. I don't agree with what others do and admins cannot see everything, so sometimes its just not their fault.
I'm very thankful to the admins who run GU, a lot goes on in the background making this game fun for all of those who take it for granted. At the end of the day, they don't have to do it ..
