Made a bulletin board spam program using AutoMouse, spammed AOL's gaming forums using it, pushing all traffic to a fake front door that lead to AllClicks/BulkClicks for .03 per click.
lol @ finding another former sports card tycoon... I used to ride my bike to Walmart with a caliper and measure the packs and buy only the ones containing "insert" cards. Purchased table space at local card shows and sold said cards. Probably the most fun I ever had making money.
