And how do you get your 'inventory data'? Aren't you scraping (or using scraped data) yourself? Oh the irony :)
No, we're a contracted provider for these customers. They ingest their data into our network through APIs or CSVs.
Makes little sense - customers upload data to you and they don't want any data back? Really?
It's not them who want it back, it's their competitors who want it.
The irony for us as a provider is that it's one of our customers (party A) paying a third party to scrape data from another one of our customers (party B) which in turn affects the performance of party A's site. We've started blocking these third parties and directing them to paid APIs that we offer.
