It is a spoofed site and while they have cloned a page at our site complete with links, there is no hack. These fake pages are very tough to get removed however so caution is urged. Please remember not to post your contact info in posts.
The spoofed page is a copy of ours and then the text of the posts themselves have been changed to appear to recommend a scammy auction site - the post in this case is recommending MLNAuctslist
The underlying website is MLNAuctslist, LLC
https://mlnauctsystem.com/
That site is a scammer auction site and the post from a well-respected site (such as ours) appears to elevate their credibility as a seller. If you google MLNAuctslist you will find multiple scam reports.
