I know that there are a bunch of sites that sell debate evidence. Frankly, I think it's a little silly (and probably against the law), and I personally wouldn't ever make the decision to sell evidence, but it's a free country.
But selling camp evidence? I know that this has been going on for a while, but that's just ugly. Kids are pretty much required to go to debate camps to be successful in this day and age of debate. So they pay thousands of dollars to a college for the privilege. That college then takes their work, sells it for profit, and doesn't give the students back a dime. I mean I know you (hopefully) get more out of debate camp then a chance to cut cards, but that sucks.
End child exploitation. Boycott camp evidence.
Luckily, it looks like the fine folk at the NDCA are making this practice obsolete.
