If you've been getting away with buying links from a quick-buck, automated link broker, Panda -- probably sooner than later – is likely to flush your rankings down the tube along with the rankings of all the other "fish" on that broker's sucker list.
When you say "sooner" can you be a bit more specific? What's the average lifespan of a scrap site you think could be? That is to have ROI.
How about if the scrapper spends $50 total to spam the search engine for few months and be at the top of the results for some important phrases in that time. Do you think he will lose?
