I've received a similar mail not too long ago. Looking into it, I
couldn't but conclude that it was some sort of phishing scam. When
following the link one was asked to provide a lot of information. The
webpage seems to be outdated, incomplete and nowhere was explained why
they'd scan the internet for anything. All in all, the page looked as
"phishy" as it gets.

For reference, below is the abuse mail I received.

Regards

Peter
