Creating a clone is basically violating all copyrights of every commenter and contributor here on Hacker News. We could all get together and inundate you with DMCA takedown for our Intellectual Property. We still retain copyright and all rights to our User Content, while we've granted YC a non-exclusive license to it. Scraping and cloning is also a violation of HN's TOS.
