Why bother? I think the mods have a good handle on the situation.
Because it's obvious she's becoming a repeat offender. Why wait for her to violate another rule, when she obviously is violating the forum's ones now?
Just smack a permanent ban on her IP and carry-out a preemptive strike?
If she'd just sit down, go and do something else, and accept her modest 10-day ban, then I wouldn't be advocating this. I didn't start trouble when I got a 30-day ban - even if it did take me five days to figure out for how long I was banned. This person, obviously, is incapable of accepting their punishment for such a blatant violation of policy and moderator ruling. She deserves what she gets.
