That sucks, dude. Am familiar with it, I've given up on seeing larger bands since ...well (shudders) ... I really am getting old, since I think Pink Floyd's Momentary Lapse of Reason tour was the last one I actually stood in line for, including online (I've tried online, but I've always failed -- now with automated everything, it's impossible to get past the scalpers). I've seen a couple big ones since then (Depeche Mode, Garbage, Nine Inch Nails, Bowie), but even most of those were in the 90's. Haven't seen a large concert in years.
I'll still see: Laurie Anderson, Peter Gabriel, and Blue Man Group every chance I get.
BTW, they're wrong to block you -- most of the scalpers have reverse IP lookup defeats.
