If your ex-girlfriend removed what she wrote from XXX then that might be the best you can hope for in the way of reputation-control. You are probably going to have to resign yourself to flooding the internet with positive content about yourself to get the negatives hidden, and you are probably going to have to forget about taking any legal action against the Korean-based XXX
The XXX website has been sued in the past by other websites for stealing their content. XXXX has been accused of scraping copyrighted photos and data from various online locations and then posting this content to its own site. Although this is copyright infringement, for which some legal recourse exists, it is hard (and prohibitively expensive) for most individuals whose content has been infringed to sue an overseas infringer, and the websites whose material has been pilfered are often not interested in spending funds to pursue another site in an overseas court (especially when their own site is drawing legal actions over the content).
The only apparent way to have the harmful material removed from many of these sites is to pay a "reputation repair" service several hundred dollars. There is a reputation repair service that is owned and operated by XXX, for example, and there are generally reputation repair services connected to the other, similar sites that post harmful content (nude photos, defamatory content, mug shots, confidential information).
It is this type of "scamming" for money that U.S. courts are being asked to address in court actions over mug shot sites and arrest sites and gripe sites that also own and operate their own reputation repair and content removal services. It is being viewed by many as blackmail (create harmful material, post it online, demand payment for its removal).
If you want to sue your defamer (your ex-girlfriend) for the harm caused to your reputation, she is the logical target. She is the one who created the mess you now find yourself in. But all you are potentially able to gain from a defamation lawsuit, now that she has removed what she has been able to remove, is a monetary award. Your reputation will not be repaired.
