You won't miss it, because staff are constantly banning her. She was just banned a week, for no apparent reason, after having just been banned a few days, for no apparent reason.
It's because these weirdos "Johnny Walker" (who constantly harasses her) and that #3 ranked girl, Maria (who VPNs), constantly spam report her. There are others who feed into it. I'd suspect people like Brandon, Boots, etc.
They constantly PM people and ask people to report her for very vague, generalized reasons. GPs are inexperienced noobs, so they cave in to the reports instead of
actually doing their job and monitoring the situation themself. I wouldn't be surprised if these bums have a Kik group where they all organize together to report her.
Sarah isn't even top 50 in wins today, sparred less than 15 times, just logged on and was banned yet again. Meanwhile, there are players who have actually been breaking rules for months, like that serial VPNer Paz and Carly (who has speedhacked openly for nearly a year now).
So, unless you're busy for the next month then you'll probably be around to see her hit 100k. But the state of the arena seems very pathetic right now (in terms of attitude and skill level), and GPs aren't helping out at all.
