Good times, good times.
I sort of miss the old days when Sandbox was free and you could manipulate the URL's to see all proposed trades, pending waiver transactions, open trade offers, etc.
I'd analyze trades offers that I had no business knowing about, tell people they shouldn't pick that guy up off waivers, etc.
I eventually made one guy so mad he waived his team. I then charted out all the pending waiver claims in order, which gave me a huge advantage on plotting my own waiver claims.
...which only pissed off more people. Everyone enjoyed talkin' trash, but when they thought I was in their computer they didn't like it so much.
