Recently I bought an expired domain, use as a pbn and repost the articles from waybackmachine as well as the logo. After several week the previous owner of the site contact me by email and claimed that it is illegal to use the logo, suspect me using the site to scam his customers, and want to sue me for over a million. I have change the logo and site title. And now is it ok if I just ignore him and continue to use the site as my pbn? I don't want to reply him as it will expose my real identity.
