The eXch exchange phishing site has been active for some time on their old domain with the .cc extension. With a simple search, one of the top 5 results is a link to the Bestchange page with an exch listing page that probably dates back to 2015. Although this exchange has been delisted from Bestchange monitoring and, as far as I understand, the cooperation will not be renewed, it would still be good if you at least remove phishing links and anything that could direct innocent users to the wrong page.
On this page
https://www.bestchange.com/exch-exchanger.html where the title says:
Exch exchanger – reviews, info, feedback (exch.cc)
Also, on the page itself, among some feedback, there is a link that is malicious today.
Their official statement for the .cc domain
exch[.]cc is a phishing link and does not belong to eXch anymore, don't be scammed by using it! (By the way can you please edit the links in your message?)
