Sorry this was from Google now I already deleted this link.
i hope it was just an honest mistake and that you are not working with them.
a bit of unsolicited advice, you should try not to recommend exchanges that you know nothing about or have not used yourself.
but if you do, you definitely should not share websites you find on google, or any other place unless the source is trusted like kycnot.me.
Thanks for update about this.
be careful with what you recommend next time, someone could lose their coins.
edit:
this exchange from the OP is a scam, don't get fooled.look what we have here, another piece of shit shill account editing their post after getting some replies to promote a scam exchange.
after darkchange.io got flagged by metamask and the domain got burned, now they are using darkchange.net.
