What do you do if you can't detect the scraping? And if you do detect scraping, how do you ensure the data you provide them is both invalid and consistent?

- jjeaff 8y agoI used a multiplier that was calculated using the date, a static secret, and a seed hashed from the sku. So it was consistent but the offset was different product to product. So that even if you manually went in and figured out the offset for a specific product you couldn't just offset all scraped prices. But once they lose a bunch of money the first time, they tend to stop trying. We tracked down one competitor that was mirroring our prices on an hourly basis. So we waited until late at night, tanked our price on a few expensive items, then placed orders on the competitors site. The human touch tends to scare off scrapers faster than a technological fence anyway.
